History is not on AJs side. Aside from Namath and Bart Starr, no Alabama QB has really seen much success in the NFL. Also not on his side is that he's backing up and having to learn from a team that doesn't have a really good QB to learn from. Another thing not on his side is that he has been in the league since 2014 and has only played in 2015. I don't know how we can value someone's worth on 3 starts, unless you are valuing him on his preseason play which isn't fair either way for him because he's playing with the 2nd string team who are obviously not as good as the first string team he's be playing with on Sundays. I don't get the hype, I don't get the want for the guy unless you are a team like the Jets or 49ers or someone like that.
Valuing someone's worth on three starts is a whole lot better than doing so without any experience at all as is done yearly in the NFL draft. Beyond that, interviewing coaches and players who work with them is another tool used to evaluate as is making comparisons to former and current players in terms of style, approach to the game, management style, fit into an offensive system and measurable tools.
Now in as much as history is concerned, those stats can be used to justify almost anything. However since you want to use a historical stat consider this list....Roger Staubach, Terry Bradshaw, Jim Plunkett, Doug Williams, Jeff Hostetler, Trent Dilfer, and Tom Brady. They all didn't win the starting jobs on their respective teams but went on to win Super bowls. BTW: 6 SEC QB's Have won SB's.
Then there's this....
Top 15 Backup Quarterbacks who Became Legends

A pretty impressive list huh? We can do this all day and night without changing our perspective, so I'd rather not. Instead I'll just reiterate the original question (challenge) that was and has been presented during this whole Cousins mess.
Who can (we) this team reasonably get without the cost in moving up in the draft or without taking several steps back to replace Kirk Cousins if he walks?
