If he wants the top 3, then he must like Edwards, Wiseman, and Ball because I think those are going to be the top 3 picks and Boston wouldn't likely need to go that high unless those are the targets.
Frankly, I'd take Ball. I think he has the most top end potential of anyone in the draft and think he'd be a pretty solid fit next to Tatum and Brown. I wouldn't be upset with Wiseman or Edwards either, but Ball seems like the guy to target.
