I like CDR, but he's being overrated here. He benefited immensely from the system Calipari runs in Memphis, with all that penetration and kick out (Brokeback Mountain, as Phil said). Perimeter defenders in the NBA are much more quick recovering than those that CDR faced in college, so it won't be so easy for him to step past them or take open shots. I think this question has merits: would he be such a good slasher without a pg that didn't demand so much help defense in the lane like Rose did? Also, he'll have to read screens and post up in the NBA and I don't know if he's good doing that. I mean, can he create his own shot in another type of offense? I don't know... and neither does he, I guess. Anyway, if we draft him, I'll watch his games again to form a more solid opinion, as I was more interested in Rose the first time.
I think CDR can be useful, especially in a team like Boston with tons of firepower and a fast pg like Rondo, but factoring defense, he's not as good as Lee, let alone Rush.
