    So whilst you are all busy making your last minute adjustments to your SC/DT teams, here at TipBetPro we are getting ready to use SC stats (amongst others) to predict the outcome of every AFL match. We’ll be sharing these tipping predictions every week on our website (http://www.tipbetpro.com/) along with key statistical insights right here at TooSerious.

    Last year we tipped 152 games correctly (72%), which was 4 more than the bookies favourites, 8 more than the Swinburne University Super Computer (we use fairly standard laptops!) and we finished 1,665th out of nearly half a million footytips.com.au users. Furthermore, 2015 was our worst year for a while – previously we have managed to tip around 75% correctly and TipBetPro finished in the top 200 on footytips.com.au in both 2013 and 2014.

    What is the TipBetPro approach and why does it work?
    Most AFL models will only use "team" based factors in modelling a predicted result, i.e. ladder position, form, home ground advantage etc. TipBetPro takes into consideration not just the standard team factors but also the individual characteristics of every player named to take to the field – including SC stats, player ranking and games played.

    So unlike other punters, we put a heavier focus on the main factor which determines the result … who is named in the 22 that week! Our experience across other sports has shown this is consistently underestimated by most “models” and that includes those used by the bookies (we also use the model to find the best value bets each week).

    It sounds obvious, and in commentary on every forum, you’ll see supporters predicting outcomes and linking it to the latest injuries or who’s returned from suspension. To a certain degree others do factor these in – however we have found that typically the impact has been understated or not enough consideration has been taken of the depth players coming in to replace those out of the side.

    Our ladder predictions – based on 5,000 simulations:
    upload_2016-3-16_8-11-0.png

    We have run 5,000 simulations of the 2016 Home and Away season with a random injury generator to test the depth of each team and determine the expected wins and probability of making the top 8. These ladder predictions not only take into account TipBetPro’s current player rankings of each team’s best 22, but also projected player improvements and declines based on each player’s age and experience.

    Without going through every team, our biggest predicted upset when compared to the bookies market (or the predictions from fellow TooSerious members in the predictions thread) is that we consider it unlikely that Sydney will make the top 8 in 2016. Sydney are a fascinating case study and there is no doubt they have remarkable elite talent, notably that they are the only side to match the Hawks with five Top 40 ranked players - Lance Franklin, Josh Kennedy, Jarrad McVeigh, Kieren Jack and Dan Hannebery, not to mention Luke Parker rapidly approaching that group. However, Sydney's depth has taken a hammering in recent seasons and the trend will continue in 2016 with the loss of Lewis Jetta, Adam Goodes, Mike Pyke, Rhys Shaw and Craig Bird. The Swans have a large group of below average starting 22 players and their youth have thus far under-performed compared to their cohort (other than the supremely talented Isaac Heeney and to a lesser extent Jake Lloyd). All this leads TipBetPro to anticipate that Sydney will be the big sliders in 2016 and only 14.1% of our simulated seasons have the Swans making the Top 8 (only 0.6% for the Top 4).

    Thanks again to TooSerious for letting us share our predictions, and as always, we welcome all feedback or questions on these predictions or anything else you find on our website – and for those with an interest, we are also doing weekly NRL tips based on a similar approach.

    Cheers

      I love statistical analysis. Particularly when it comes to tipping- I've always through that a player-level approach to tipping was an approach just begging to be dove into.

      I actually got started on writing one a couple of years back, based on SC scores- using the assumption that the higher team SC score usually wins the game. But was never happy enough with my individual-player SC predictions to release it to the public.

      Gunna be interesting to see how it plays out- a lot of Swans are gone, but surely others stand up to take their points?

      Also, just quietly, based on a 0.6% change of happening, you can get $1.80 (sportsbet) on Sydney missing the top 4 (exotics-Ladder Finishing Postion). Long time to tie up cash on a $1.80 bet though. :D

      Also, 2.9 wins for the Bombers? How many injuries did the other teams need to cop for us to manage that? :D

      The Swans are intriguing. Their top 10 players are elite and as good as anyone bar Hawthorn so they can still be a threat if the depth stands up ... but gee that depth is starting from a long way back. The importance of the likes of James Rose, Zak Jones, Brandon Jack, Dean Towers, Jake Lloyd, Gary Rohan etc has never been greater and they really need to stand up and establish themselves as clear starting 22 quality players for the Swans to be a threat in 2016. And if they don't, particularly if the Swans cop a few injuries to their big guns, it could be a very long year for Swans fans.

      As for the Bombers ... well that's an average ;) ... we do have 139 season simulations where they go through win-less and a further 774 where they win just the one game! TipBetPro do believe though that the Bombers selected wisely with their experienced top-up players and they have a core of players that are projected to shift into an up-swing in their career in 2016 (Joe Daniher, Zach Merrett, Jackson Merrett, Martin Gleeson, Patrick Ambrose etc). So although TBP have Essendon finishing wooden-spooners in 64% of our simulated seasons - if they have a decent run with injury, we don't anticipate them being the competition easy-beats that many others are anticipating.

      I understand the joke, but honestly can't believe Tiges for 9th is still a thing since we haven't finished there since 2008 therefore 7 seasons have passed since. Port, West Coast, Essendon*, St Kilda, North Melbourne x2 and Hawthorn have finished 9th more recently than the Tigers.

      *Obviously coz drugs, otherwise would've been Carlton

      I can buy Sydney having a bad season or failing to be a contender but not finish 12th. Not with their forward line or midfield. Their defence would have to suffer a lot of injuries for that scenario to occur

      Losing a final to a team that really finished 9th helps keep it relevant too.

      Midfield we are with you for sure - Kennedy, Jack, McVeigh, Hannebery and Parker are as good as starting 5 midfield as there is in the competition. However, the depth falls away sharply after that (albeit Mitchell experienced a considerable spike in rankings towards the end of 2015) and the ruck situation is problematic with Sinclair/Tippett not rating well when compared to some of the other top echelon sides.

      Forward line we are not as bullish on Sydney as many others. Franklin is on a declining trend and is no longer the clear top KPF in the competition, Tippett we expect to be more prominent in the ruck, McGlynn is a handy small forward/midfielder but probably just below the elite small forwards in the competition and after that you start to head down to the likes of Sam Reid (consistently under-achieving) and Isaac Heeney (supremely talented but youth/inexperience almost always results in inconsistency). Compared to the likes of Hawthorn and West Coast (and we would argue Adelaide, GWS, North and Richmond amongst others) the Swans forward line we don't necessarily see as a particular area of strength.

      Defensively the Swans are now poor. Whilst the Swans boast solid small/mid defenders (Smith and Rampe), they have declining performances from their KPDs (Richards and Grundy) and very little in the way of quality running defenders unless they rob from the midfield to pop McVeigh back there.

      Can the Swans finish Top 4 and make a fool of us? Of course - with that elite talent, it only takes the depth to stand up and a good run with injuries and Sydney have the potential of a contender. However for us - an above average but not perfect midfield, above average but declining forward line, below average defence and competition worst depth across all positions adds up to a very much middle of the road side in 2016.

      Can't say I agree. That midfield had plenty of depth, as McGlynn showed last season and with the likes of Heeney, Mills and Hewett there's not shortage of youngsters coming through. Don't have any concern with that line.They do rely on their key position players and it is possible that they don't make the four I don't think that's a guarantee, but without any major injuries yet I don't think they can be written off as a finals team and labelled as likely to finished 12th, which was my argument. Their forward line is better this year if you consider Sinclair will spend time in it and I even if their ruck combo is untested he's probably an upgrade on last year's Pyke too. So 5th - 8th is my range on Sydney.

      I am comfortable predicting they will finish below the giants, purely on awesome alone
