The constraint on a "jump" next year will be playing time. Except for AG, none of the jump candidates is likely to get the playing time needed to show Carlton-like improvement.
Sid will be contending with Vital and Bouknight at the 3, which may force him over to the 4, where I expect Akok and a healthy Diarra will already have pushed Polley to the bench. Diarra, despite his height disadvantage has absolutely the best shot to be first backup at the 4/5.
All this is complicated by the fact that Gaffney is likely to earn his way into the starting lineup alongside AG. This will create the crowd scene at the 3 and diminish playing time for each of the candidates.
Net-net, the biggest jumps are likely to be made by players already solid in their positions; namely, AG and Josh. If there's a wild card jump, it's Diarra.
