20Matt Cassel - New England Patriots
While Tom Brady seems like he's going to be around for another few years, the Patriots may yet again hold off on drafting his successor, considering this year's QB class isn't all that strong anyway. For now, the Patriots will just give Brady a backup he's comfortable with, and who
may be an upgrade over Brian Hoyer.
In the case of Matt Cassel, he has four years of experience under Bill Belichick (and Josh McDaniels for that matter). While it will take some time for him to understand the offense again, he’s a great fit to bring in, and keep Brady comfortable, knowing his successor isn't gunning for his job.
