Re: James Johnson vs. William Buford vs. Travis Leslie vs....
Getting Kemba Walker at 25 would be amazing. I don't think he's gonna be an All-Star or anything, but he should have a long and successful career.
Everyone else you listed? Morris could be better, but like you said, theres no real need for him. Leslie and Buford I think, best case scenario, will be just as good as James Johnson.
I wouldn't have been against keeping the first rounder, in fact I didn't like the trade when it was announced, but I don't think there is going to be a huge difference between what we have (Johnson) and what we could potentially have.
