I know it doesn't mean much, but Polley had as many blocks in this game (1) as Cobb has had all season. He's also had more blocks this season than Cobb has had in his entire career. Hurley has made it clear before that his system requires a rim protector at the 5 spot and Cobb is not that.
People really dog Polley for his defense. Granted I couldn't watch Iowa or Manhattan, I thought he's done pretty well this year for being played out of position
