I'm of the opinion that Keenum might actually be better than Bradford. Bradford's been injury prone and has never passed 8 wins in a season before. I also think he might be having one of those Nick Foles kind of years like 2013 when Foles came in and surprised everyone with his high level of play. Foles that year, Derek Anderson in 2007 and a few others have had those few years where everything clicked and they rolled with it. I think he'll be a 1-year wonder just like those guys.
My thing is this. There are some QBs who you could put in either Bellichick, Payton or McCarthy's QB schools and they'd never get fixed. For example, remember the Pats brought in Tim Tebow that one year and were unable to fix him. They also tossed Ryan Mallet out after a couple seasons and decided he was too broke to backup Brady. Whereas Jimmy Garropolo and Matt Cassel back in the day did get it, until Cassel left and got ruined by KC. Coaches can only do so much to fix bad QBs, and it's ultimately up to the QB to get it. I mean ... Brian Brohm, drafted him pretty high, we kept hoping he'd turn out to be a hot commodity backing up Rodgers, and he failed. Matt Flynn got drafted with scouts putting him on a lower scale than Brohm, yet he turned out quite well running MM's offense. It just goes to show that it's up to the GM to be able to evaluate QBs properly, and in some cases they fail bad at doing so like Hundley.
