Friendly reminder that Summer League doesn't really tell you if a player is going to be good... it just kind of shows you who is going to suck.
Consider that the league is made up primarily of undrafted amateurs. Most of the guys playing we ok in College, but not good enough to be drafted. So if you're the #3 pick in the amateur draft, common sense says that you were probably one of the top amateur players. These are the same peers you were better than in College - so you should be better than them in Summer league. If a top draft player DOESN'T put up big stats in Summer league, it's time to start panicking.
Brown looked good. He's supposed to look good. Hopefully it eventually translates to playing against pros.
I agree with Lar here (words I don't often type).
Summer league isn't going to tell you who is a star, it's going to tell you who is a bust.
I think we can chalk up Clench's and others hate to a lack of patience. A few people vocally wanted Danny to trade for their personal binkie on draft night. When Ainge elected to use the pick instead, those folks transferred that hate to the pick. So it wouldn't matter who we drafted at #3 - Bender, Brown, Hield, etc. - they'd be saying the exact same things about that player.
I wasn't a Brown fan at the start of the draft process. But the more I watched and the more I heard, I've come to believe that this kid found a great fit in Boston. Perfect place and a great system for showcasing his talents. He's also one of those guys whose skills translate better to the NBA than they do college basketball. Westbrook was one of those guys - 12.7 ppg, 4.3 apg as a soph yet he's all-world in the NBA. I think Brown can make a similar leap (though I'm not predicting he will be as good as Westbrook) so I've put my prediction in my sig. We will see how it pans out.
