'06-'07 team with a healthy pierce is pretty comparable to this year's squad.
The '06-'07 squad that was on the floor most of the season was quite a bit worse than this year's team.
This year's team has to be better.
A stronger top-3 players (Giving credit to Rondo/Green for experience, Rondo as better able to improve the play of others), and pretty strong, experienced supporting cast (Bass, Lee, Wallace, Hump).
'07 Perkins wasn't the guy he became with KG. Our PG committee wasn't very highly regarded, either.
I'm betting high on Sully/KO coming together in a couple of years, and making this group clearly better than the other group could have been if kept together (for whatever point such an assertion may have).
