Last night at the TD Garden I got in early enough to watch Kendrick Perkins work on some basic big man drills with assistant coach Roy Rogers. After Perk greets Celtic play-by-play man Mike Gorman, he does a few basic pick-and-roll drills, slamming home some baskets. We also see Perk shooting free throws, flashing the low post, and backing down ghost defenders while working on a variety of post moves.
Perk shows off a little fade-away jumper on the baseline as well, while moving around very quickly. Two things stuck out at me: 1) His lateral movement was pretty good as he is planting and pivoting relatively hard. 2) He is in phenomenal shape for someone who has been injured/rehabbing since last June. Perk has definitely not been loafing around as evidenced by his svelte physique. His return couldn't have come at a better time as Jermaine O'Neal might be getting surgery.
All in all he looked solid, here's some video of him:
