DD cannot and should not guard Sf's in this league. he may be long, but hes not big enough. unless he puts on 15-20 pounds this summer(doubt it) he shouldnt play sf thus no need for turner. curry would be a nice pickup with the pic, bargs, and whoever else they want other than DD, Ed, Amir.
Yes, DD cannot guard starting 3's. At best, he's good against bench 3's. As for Curry, I'm done for having him here.
