I reckon Witt's and a first rounder would be plenty for some of our GWS & GC targets. Witt's may turn out to be the next Sandilands, but I reckon he's surplus with Grundy there. Get a Ben Hudson type in to help Grundy if he gets injured throughout the season, etc
Or if we can develop both witts and grundy to be able to go forward and hit the scoreboard and be the most lethal ruck/forward combo in the league. Both are 23 and under, their best years ( by ruckmans standards ) will be 24-29.
The AFL will be slowing the game down again, far fewer interchanges. The return of the big men is near. Back them in to lead our rucks for the rest of the decade.
