JJ is the best athlete of the 3 and the only one that, right now, I could potentially see having an NFL future at another position.  If he doesn't win the #2 spot clearly in spring/fall camp then I could see a move to where he still works some at QB, but works at another position where he could see the field and be utilized quickly.  Let us not forget that 2 seasons ago Dobbs was #4 on the depth chart and was starting at seasons end.  Last year he was #3 and is now being talked about as the best returning QB in the SEC (including a QB that received early Heisman talk last season).  QD is coming off surgery and may be limited this spring, which could give JJ a slight advantage.  Both Jones and QD are far more advanced as QB's in regards to training and experience playing the position.  This will by far be the most interesting position battle to watch this fall, but due to all the factors I have stated above, it is not that much of a stretch to see all 3 of them still on the roster in '16.
