Why is Perk playing so few minutes? How are these for reasons: according to 82games.com, Perk is one of the worst centers in the league at getting tips around the basket (an extremely important part of any big man's game). Perk is also one of the worst, if not the worst big man (depending on how you interpret the stats), with the ball in his hands, just about leading all centers in categories of offensive fouls, dribbling turnovers, passing turnovers, and other turnovers. Perk also, when you combine how often he gets blocked on jump shots, dunks, and close shots, leads all big men! He's just too slow and predictable. Opposing players make him eat the ball more than any other big man in the league. Oh yeah, Perk basically gets assisted on his shots more than any big man in the league, which means when he doesn't get gift wrapped a wide open shot from Rondo, Pierce, or Garnett, he's a walking disaster.
Besides those glaring, backed-up statistical flaws to Perk's game (82games), he's by far one of the slowest and least skilled beg men in the league. He is also a bad free throw shooter, even as far as big men are concerned.
But I'm sure someone will copy and paste this post and say, "No way! Perk is a beast, and he's great on defense!"
