Because Felton can actually defend and run the pick and roll?
Don't get the Nate Rob comparison at all.
Felton's a definite improvement over Duhon, but I have no idea what his asking price will be in the summer.
And no we cannot resign Lee if we sign LeBron/Felton, because we have to renounce his Bird rights to gain the cap space necessary to sign LeBron/Felton.
