It is true, however, as the original poster points out that we seem to lack any coherent idea of what we're trying to do defensively.
Which is mind-boggling, because the frontcourt personnel and the coaching staff is virtually identical to what we had last year, and Garnett doesn't look like he's lost a step defensively.
Defensively:
Stiemsma > Collins/Wilcox***
Pietrus > Green
Bradley > Lee
Dooling > Terry
*** This is the big one. We still had a guy protecting the rim when KG left the floor. Steamer did a ton for this team.
I disagree with these assessments, it's more like this:
Defensively:
Collins > Stiemsma (Collins is a solid post defender, Steimsma was a highly overrated shot blocker who sucked as a low post defender
Green> Pietrus (Pietrus was hobbled, a shell of his former self)
Bradley > Lee
Ray = Terry (you can't ignore Ray, our starter through the playoffs)
