I think that Harris would get abused if he logged a lot of minutes at PF. He's giving up way too much height, and in a lot of cases athleticism. He's going to have to play SF, where he could probably be a passable defender. Most SF in the NBA don't play much defense anyway. I like his offensive game, but best case, he looks to be a spot shooting forward who might get you 15-17 points a game. I'm not saying that Harris doesn't have potential, but the way people are acting, the Bucks gave away a perennial all-star. I don't see it. Mind you, I could be completely wrong on this, he's still a kid and I don't think that any of us have seen him play enough to be sure. No matter what, he's going to need time to develop, and by that point he's going to be up for restricted free agency, meaning someone is likely to take a big gamble on him.
