JJ is a combo guard, but imo he is more of a 2 than a 1. However he gives the Hawks a lot of flexibility as to who they play next to him. He can play well with another combo guard or a pure pg, i don't think it really matters.
The NBA of the future will not have set positions and the Hawks are the team of the future not the present. They will never be successful in the present, they just are not built for it. They will always look into the future! That said, they will never draft a PG because in the future PG's will be a thing of the past. The Hawks plan on playing 4 SF's and a 12 man at all times, they may never win in the present but they will sure look futuristic while your losing.
