I would be pretty surprised if one of the 5 QB's makes it to 15.
I would only be a little surprised as there are plenty of scenarios where it plays out this way. The problem even if one does slide is that we get stuck with the one no one else wanted, not the one we want. That alone may be reason enough to trade up.
All the 4-14 teams, Falcons, Bengals, Dolphins, Lions, Panthers, Broncos, Cowboys, Giants, Eagles, Chargers, Vikings have a solution at QB currently. Someone said in an earlier post that if a team's current QB bombs out, the team is bad, and they are in position to draft a QB later. It just seems like a bad value play for these teams to take a QB for redundancy or future consideration over taking a player that can help them right away.
If these teams do gobble up all 5 QBs before the Patriots pick, we will end up with that much better of a player available to us. As I said, I would be thrilled with Parsons or Paye and maybe even some one like Devonte Smith slides down to us.
