Wow, that's a pretty crazy list, I gotta say. I'd agree re: Brady, Manning, Rodgers, Brees, Wilson, Roethlisberger, Ryan, Luck, and Newton. But Rivers, Romo, Foles, and RG3 as definites? In my book, they're all borderline at best, along with Stafford. Of the rest (Cutler, Flacco, Tannehill, Smith), I'd take Kaepernick over them and never think twice about it.
Which puts Kaepernick right around the top 10 mark. Given his age, potential, and the length of the contract, I don't see that as a significant overpay. Within a couple of years, that deal might not break the top 10 for AAV on QB contracts. At a bare minimum, worst case scenario, I still know I'd much rather be paying Kaepernick that kind of money than someone like Flacco or Stafford.
Ironically, a lot of the arguments being used against Kaepernick in this thread are pretty similar to the arguments that were used against Brady earlier in his career. Yes, he has a very strong team and coach around him. But it's no accident that they're in the NFCCG every year. And yet we have people saying that they'd consider taking Alex Smith over Kaepernick? We already saw that play out: Kaepernick is better, period.
And FWIW, I'm saying all of this as someone who doesn't even really like the guy. He seems like a ****,but that doesn't make him a bad football player.
