Exum being aggressive would most certainly not be a detriment to this team. It would help us win more. Exum helps us win because he is a good defender and Burke was atrocious. This is why Kanter said he never had a true point guard. Our other core players (Hayward, Favors, Gobert, Burks, and Kanter while he was here) are probably all a little better than we have seen. Especially Favors and Gobert (because they are most dependent on PG play) because they've rarely played NBA ball with a legit PG. Dante helps us win by comparison to Burke. Burke was bad at offense and defense. Dante is just bad at offense.
I still really like Exum, and in no way think he will be a bust. I just really like Lavine and think he projects as a generational talent with his size, speed, athleticism, passing, and shooting. Then you factor in his work ethic and desire. Sure, he's not the smartest, but he's also not as dumb as you all say. Sometimes it takes awhile for the brain to catch up with the talent. How often is it that we see a prospect who projects so well in so many areas? A lot of athletes can't shoot, but he can... that is the ultimate weapon.
