I am a Betting man!!!
Well, if you look at Dell's track record, it won't be an UFA. It will be a guy between 23 and 26. And it will be a high character guy. That leaves us with:
Draymond Green
Tobias Harris
MKG
Jae Crowder
Jimmy Butler
If he does break trend and goes after an UFA, I think Demarre Carroll is a perfect fit. But if I had to bet, I would go with MKG.
