I put CDR pretty even with Lee on my wishlist (although still behind Walker...but I certainly understand why they would pass on someone with such an injury history). I think they are both similar in that they both could step in almost immediately and be contributors (and make T.Allen expendable), while still having the upside to be a starter in this league.
They also are pretty different though. Lee is much more of a shooter in the Rip Hamilton mould. He likes to run around, off picks, and can be just as effective playing off the ball, then having the ball in his hands.
CDR on the other hand is more like Paul Pierce (in style, not ability). He is a slasher, who is great at making his own shot.
I think CDR has a little more upside, but I think Lee will fit into this team a little more right now.
It's a tough call, but if either of them fall to us, I would be very happy.
