So, the surmise here is that Leroi is DD's source if he is in fact legit?
QB evaluators seem to still be following the old school parameters . . . the sort of criteria that brought us EJ. (And I liked EJ and held out hope much longer than most.)
Nevertheless, Cousins, Smith, and Darnold, who we will not be in a position to draft most likely does not sound like a good plan to me.
Personally, I would not dismiss Mayfield from consideration.
