Still needs to improve his 3 point shooting and shot selection, but he's an interesting offensive talent that can be productive when given the chance.
If I had to sum him up in one sentence that would be it.
I watched a good bit of Brooks his rookie season and the potential there was obvious, but I think there is a clear ceiling for him. He is never going to be a starting 2 guard on a team that is competing for a championship.
At best he is going to be Nate Robinson/Nick Young type 6th man instant offense type of player. At worst he is going to be a talented scorer on a Euro squad. If I had to make a prediction, I think he is going to end up being a poor man's 6th man or a rotational SG on a good team (Leandro Barbosa).
I don't think he is going to be a Celtic long term though. With a bit more polish he would be a great add in to one of those mega trades for a superstar. He will get plenty of minutes to showcase his talents this year and then could be moved in a large deal down the road or at the deadline to a contender needing either scoring or that suffered an unexpected injury.
