It seems like a lot of the QB needy teams at the top of the draft are not so sure they want to spend those top picks on them - Clowney, Mack and Watkins all look a lot more like sure things than the QBs. Other than Bortles, I can see the others staying on the board a while, but if so I think the team that will start the run on them is the Jets at 18.
Of course, this is the season on mis-information, so 5 will probably be drafted in the top 10!
