Kendrick Perkins  leads the Celtics  in blocked shots this season and also is one of the top swatters in the NBA. His 29 blocks through 14 games ranks him seventh overall in the league in blocks per game (2.07) and blocks per 48 minutes (3.73). He ranks third in total blocks among all NBA centers and second in the Eastern Conference.
Perkins gave WEEI.com a glimpse into the mind of a shot-blocker:
Good block, bad block: ‘A good block is when you can block a shot and keep it in play. A block, rebound, keep it in play where you get the possession. A bad block is when you block it and block it out of bounds and you’ve got to play defense all over again.’
Timing is everything: ‘Timing, you’ve got to read. I think you’ve got to read, see what’s going on. Sometimes you’ve got to judge whether or not you can actually block the shot. Is it worth trying to go and block it? So it’s all timing and decision making.’
Judgment call: ‘Well, you can tell if a guy’s out of position as far as just how he goes up, if he’s kind of capable of making the shot. If a guy goes up out of control, you kind of want to fall back and just wait for a rebound.’
Making the move: ‘When it leaves his hands, then you jump up.’
Perkins has used his judgment to make cautious decisions on defense. He leads all Eastern Conference centers in blocks per personal foul (.74). Perkins shows no signs of letting up this season, either. He is averaging a season-best 2.5 blocks per game on zero days’ rest.
