Oooo, good question.
IMO, I think it's between Horford and Lopez. Noah and yes, even Bargs
are too one dimensional to be an all-star, aleast for right now. Noah rebounds, Bargs
shoots. Loez and Horford are both very good "true centers". They rebound, block shots, and can score when called on. Right now I'd give the edge to Horford, since his teams was won a game.
