Here's a video of Jackson's last season highlights. As you'll see in the video, the majority of Jackson's scoring come at, or near the basket. He definitely had a habit of passing up open looks on the perimeter to attack the basket. While he was highly successful at it in college, I think he'll find it harder to do at the NBA level if he can't make them defend his jumpshot. He is a good ball handler, and has s good first step, so I think he can still be very effective off the dribble.
He's a very unselfish player and is a willing and very good passer. He plays off the ball very well and is constantly moving. As you'll see in the video, he's a good finisher, and relentless around the basket fighting for putbacks. He also rebounds out of his area. Defensively he's a monster. He's a very good weakside shot blocker and gets more than his share of steals in the passing lanes. He needs to add strength, and he needs to improve his jumpshot. If he can do both those things, your looking at a player with star potential. At that point, it becomes about how much of an issue you want to make of his off court incident.
Let me put it this way, Jackson didn't go up in the stands and punch a fan the way Marcus Smart did. And that was just one of the incidents with Smart. He didn't get disgusted and walk off the floor while play was going on, and have to be physically shoved back onto the floor by his coach, the way Lance Stephenson did. Compared to those two, he's a freaking angel. Just trying to give a little perspective.
