How will this team improve next season?

[Fencer reregistered]

1. Rondo -- better shooter.
2. Rondo -- fewer bad defensive gambles.
3. Perkins -- fewer fouls
4. Perkins -- more consistently bringing his A game.
5. Perkins -- more range on his jumper
6. Garnett -- better judgment about when to score aggressively
7. Pierce -- slightly better conditioning
8. Ray Allen -- fewer bad turnovers
9. Posey -- fewer bad passes
10. Powe -- better defensive rotations
11. Powe -- more range on his jumper
12. Davis -- fewer fouls
13. Davis -- fewer turnovers (per minute)
14. Tony Allen -- health/everything
15. Cassell -- Gone/allowed to stay because Ainge believes he'll get over his chuck-first approach

I'd like to add

16. House -- Better back-court dribbling

to the list, but I have to think he's worked on that a few offseasons already, and has maxed his ability out.
