ONLY way I see him coming back is if we lose in the National Championship game or something of the sort. And even then, its iffy.
I see Barron playing a big role in the defense. Much like Eric Berry for defense. It'll be hard to "QB" from Defensive Back, but I think a true Defensive QB is at LB. So I suspect Donta'a or a plethora of people combining. With these Saban recruits coming in, they all are buying into the system so it'll be AMAZING to see.
