If EJ Totally falls apart this year, I believe, the team's plan is to have Orton play out the year and next year then in 2016 see what they can grab. Of course, this depend on whether or not the current leadership is still in place. Unless there is an unbelievable value in the later rounds I do not expect them to draft a QB next year.
Surprisingly, it doesn't seem as though Heisman QBs do to well in the NFL. I wonder if this is a sign the that that committee is really not finding the best players and really basing it off popularity/Team W-L record.
