I watched a lot of Barnes at UNC and the thing that stood out to me the most in terms of flaws was how much he struggled to fit into UNC's untempo game. Even with the best passer in the in country, Barnes seemed to prefer half court isolations ala Carmelo. Not sure how that fits the direction we're trying to go in with Rondo but it's something to look out for.
If ISOs are what he loves, then thats crazy because his shooting % after three dribbles is beyond awful. Catch and shoot, in transition, pull-up off one dribble are all areas he excels in. When he tries to dribble and create, he struggles and it stuck out this season.
People say he played with a bum ankle. By the end of the year, he couldn't even dribble past big men who came out to guard him on the perimeter. He had zero burst and looked slow.
Now that his ankle has healed, he put up the second highest vertical, fastest 3/4 sprint and one of the best shuttle times. There is no way a guy can go from looking uber-slow, to practically acing the combine, without something happening to him. The ball handling is still a concern, but at least you know he is a very athletic, strong body, well suited to play the 3, measuring a legit 6'8" with a wingspan close to 7ft.
Someone mentioned in another thread how Ainge has targeted prospects with big hype/recruiting out of HS but struggled in college (Avery Bradley was one of the most recent examples). Barnes is in the same boat. #1 recruit in the country, failed to live up to it. He was so highly touted, but ended up leaving on such a sour note, leaving a real bad taste in your mouth.
I don't think Barnes will ever be a franchise type guy, but a solid #2 option on a contending team? He definitely has potential.
It's almost too bad he had such a good combine, because he could have slipped in the draft. Im starting to get the feeling he won't be there past 4 and it will be hard for the Celtics to get a pick that high.
