Very important. At the moment he is named on the bench alongside Blair, Beams and Wellingham, with Wellingham being in the 4th spot (I still have no idea if that means anything) The only other options are Buckley, named in Krak's usual position on the Wing, and Goldsack, named on the Half Back Flank.
very good question - does the interchange sequence mean anything? Is the fourth names the sub? Any concrete TC type evidence? regards chels
