Before last season everyone had him pegged as a top five PG because of his all around game. Last season was a bit of a down year as it was filled with injuries and whatnot. This year I think he will return to all-star status. Back problems are serious because they usually become something that never really goes away so hopefully he will be able to play through whatever pain he is going to come by.
I think Baron will be back and better than ever. Those stats above sound okay to me, but I'd think that he will get about three more assists per game.
