Statistically (points allowed per possession), I'm pretty sure that is inaccurate. When the Jazz allowed the lowest FG% in the NBA, they were still worse than last year's team in points allowed per possession.
But I'm feeling lazy. My point is blocks are an overrated stat. A team has to be able to achieve them and be a threat enough to achieve them. But any singular defensive strength doesn't mean much because there are so many variables and components. For starters, what is the QUALITY of your individual defensive stats (D rebs, blocks, steals)? Nobody that knows anything thinks Chris Paul is a great defender because he can't or won't stay in front of his man. Boozer didn't play full defensive possessions so he could get position for boards and/or transition baskets. Marcus Camby can't stop anybody one on one.
It's a team thing and it's about effort and not making mistakes. Getting players to put their bodies on the line to get charges, save possessions from out-of-bounds, and going hard for the ball on the boards. Getting players to get on the same page and communicate when implementing a defensive scheme. Reading the scouting report.
To me, "defensive stats" are one of the weakest indicators recorded. BPG is probably the strongest of the individual indicators, but it means very little in the scheme of things.
If the Jazz can somehow learn to bring their rebound differential up to league average/0, they're going to be scary good. That is the biggest and most consistent problem with this time by a mile.
