Chandler was injured, played too many minutes per game, had too little team support, and could never afford to foul out of games, which made him too worn down and passive.
I am expecting better team defense and considerably more backup for Chandler than last year.
In particular, with Shumpert at the SG and MWP on the floor, I expect less switching on screens and fewer guards breaking us down, which will mean fewer rotations inside, and better interior defense overall as a result. Hardaway can also potentially help us in this regard as well.
Team blocks last year ranged from 3.2 Miami to 6.9 Bobcats. The Knicks were at 4.0.
Bargnani's defense improved last year, and might improve even more under Woodson. His best year in Toronto, he blocked 1.4 shots per game which is not terrible. I think with some focus and work, as well as a better system, he could get that closer to 2 per game. However, even if Chandler and Bargnani average only 1.5 blocks per game each , and Stat and Martin close to 1 each, and everyone else close to 1 total, that would mean somewhere in the realm of 5-6 blocks per game for the team, which is very respectable.
Stat is not great with the defensive footwork and rotations, but can block shots. I actually like Jerome Jordan defensively, and think he is under-rated offensively. I would have liked to see us land Dalembert, but Tyrus Thomas is still worth a look IMHO (or some other backup shot blocker). I am less sure about Jeremy Tyler and Earl Barron defensively, although they do provide us with some offensive options we lack otherwise. At worst whatever younger backup bigs we select, they still provide Chandler with some minutes on the bench.
That means Chandler can play much more aggressively for fewer minutes which should make him more effective when he is on the floor.
