the two years Bibby played at Arizona he averaged 5.5 apg, The last 3 seasons Jimmer had in college he averaged 4.4 apg.
So I think your madly underrating his passing/point guard skills, yah hes not AS GOOD of a passer as Bibby was coming into the league, but hes pretty damn close and he was a way better college scorer. He does have the court awareness, willingness, passing ability that Bibby had so I dont know how you can say he will never be a PG.
You gotta remember Jimmers team was not that great in college scoring wise so he was asked to take that burden on himself, he had to score that much to help his team win.
With better players sorrounding him in the NBA I can see his scoring dropping and him becoming a better playmaker cause now he will have the scorers to pass to and get asts from.
