I'm probably the only who would say I would not try to trade for Harrison Barnes, not until he learns to dribble at least.
I understand all the potential talk about him last year, but he's regressing and he's looking like he's going to be just another complimentary player. Barnes fed off Klay Thompson and Steph Curry during the playoffs, but on his own he had a hard time.
His handles are mediocre, making it difficult for him to get the rim despite his athleticism. His shooting form is great, but his shooting is inconsistent. He lacks confidence and when it's shot, you're in for longer stretches of bad games that will include bad defense. He doesnt have a good BBIQ, often passing on open shots for pump fakes, bad court vision and can't dictate mismatches (he had A LOT). I won't pay a first rounder for a player like that, no matter how young.
He had the floor to be the Dubs' 6th man in that bad second unit, and he's one of the reasons it was bad. He should have been THE MAN in that bench mob, getting all the plays and be the reliable scorer but he did not.
Outside of being a better rebounder, Jeff Green is better than Barnes, and may end up being better after their careers. He may play well with Rondo, who knows? Rondo can set him up for easy shots better than Curry I guess. But don't ask for Barnes to be ago to guy on offense, he just isn't that guy.
I'd certainly would not want to pay a high price for HB. And if we are, let's hope that Brad Stevens can fix his dribbling and confidence, because we're going to have a ton of head scratching moments.
