Rivals.com does not even list Hubbard yet as Bama commit, even though they have a story about his commitment on BOL. He is currently unranked on Rivals, how that can be I have no idea. Bama is #2 overall on the Rivals.com Team Recruiting Rankings without him listed. So he won't have much of an affect there unless he gets rated higher than not rated at all. lol
