I wouldn't put a lot of emphasis in the Summer League, but Love is my favourite player of this draft, from a purely aesthetic point of view. He'd have been my 3rd pick. Tallpaul makes some very good points with which I agree. I still don't know how effective will he be when facing taller, larger and quicker NBA post players, but I think he'll figure out a way of being good. In fact, I believe he'll be a major offensive contributor to good teams, delivering lots of wins. In a fast paced team, his outlet pass alone can be a difference maker. But, essentially, he's very enjoyable to watch. Yesterday he made a full-court pass from the chest after, and in the same motion of, a defensive rebound that was absolutely insane. Even a blind Kwame Brown would catch that ball. The kind of stuff that only a handful of players in a generation can make. Highlights reels should be made of plays like that, not windmill dunks.
He's also a fundamentalist, worships the same God that Duncan. Great screener, helped a lot guys like Westbrook and Collison. Excellent at the pick'n'pop and the step back shot is one of the bests I've ever seen in young players. Outstanding court awareness. He'll struggle defensively when facing certain matchups, but, again, he's very solid ( Howland is really great teaching defensive fundamentals; I wouldn't mind seeing him in the Celtics coaching team, by the way).
There are shadows of McHale (the crafty post moves), Walton (the passing and understanding of the game) and Laimbeer (the leadership and the ability to be decisive doing small things and playing with confidence despite some limitations) in this kid (yeah, I know it sounds lame to compare a white player with 3 other withe players, but those are the guys tha came to my mind). If he was a couple of inches taller and a little bit more quick, he'd be a monstrous player, barring injuries.
