Speaking of stats...
Dak had 2,996 passing yards and 939 rushing yards at the end of the 2014 regular season to go along with 24 Passing TD's, 14 Rushing TD's, and 1 Receiving TD. He was completing 61.2% of his passes and had 10 interceptions.
This year he's on pace to end game 12 with 3,176 passing yards, 581 rushing yards, 21 passing TD's, and 11 rushing TD's while completing 66.9% of his passes and throwing (maybe) 2 interceptions. The Troy game really screwed him (and is factored into these numbers).
Boykin got 4th place last year (and no invitation) with 3,714, 642, 30 and 8 (plus a receiving TD) with a 60.5% completion percentage and 7 picks.
However, this year's field isn't as deep. We can objectively compare Dak to pretty much everyone behind Fournette and Boykin, and the gap to Boykin isn't insurmountable.
Honestly, Dak probably needs to get to 35 TD's with 2 or fewer picks to have a realistic shot at an invitation. That means averaging 3.5 TD's per game....tough sledding given the schedule.
