Until we have someone better to fill his shoes, this topic is irrelevant. If he is too slow, that sucks. But who is his back up and what are their shortcomings that may not be speed but some other deficiency altogether that may put us in a worse position? Ultimately, if Donaldson can continue to work on his craft (and not be foolish enough to declare early) we will have gotten 4 years out of this kid and perhaps he could be a stepping stone to a new generation of Canes OL that are Greer suited to play the position. Ripping the kid with no better option is a giant waste of time.
