Walsh for mine is positional. As a central midfielder he was elite last year. From round 11 when he moved into the guts rather than the wing his average is good enough at 118. As a winger he's not a good enough ball user and doesn't do enough else to really push ahead.
Will be interesting with their mix, Cripps is obviously ahead of everyone but does Williams push him back onto the wing? They have so many HBF types with Doch, Saad, Newman, SPS, O'Brien and Williamson on top of Marchbank, Weitering, Plowman and Jones down back, it's hard to squeeze them all in without seeing a couple maybe move to the wing/midfield (Doch, Newman & SPS make sense for these moves to me if anyone).
Their preseason game will be very telling. Martin, Kennedy, Dow, Curnow, Murphy, Williams, Setterfield, Fisher and Gibbons all pushing for midfield minutes also. Personally I think they push Murphy on a wing with probably Newman and go with Cripps, Williams and Walsh as their first midfield group and then Curnow, Kennedy/Setterfield and Martin as the second rotation but it remains to be seen what they do.
I like Walsh but probably a bit too much risk given what he has to do at that price. The jump to 110+ over a whole season is a big one but he does have the engine to do it at least, just needs the position. I think if they're smart that Walsh should be in the guts, he looked so much better there than the wing but AFL coaches are notoriously dense.
