Sheed is hard to guard because of his range and because he plays on that Detroit team where you're basically manning up against five instead of one since the ball moves so well.
Kaman impresses me because of his size and grit. He's got that mean streak in him too.
But yeah, I'm surprised he didn't mention Duncan. He might not do alot offensively, but he's efficient AND he scores with the same moves. Maybe because he only plays Duncan three times a year (including the ASG).
