he was injured

he had two surgeries that offseason. That said, yes, he was terrible in 2015.

He beat Gabbert out the next year and played pretty well on an awful team. I could link to that, but my guess is that you can find it yourself.

I can still see an awful lot of Green Bay Packers whiffing on him in the playoffs (twice).

Nobody is saying that he's a sure fire hall of famer, but if you're going to compare him to Blaine ("that's not a name, that's an appliance!") Gabbert, you could at least be honest and include the entire story. The truth is that for the majority of his career he was an above average to very good qb. In the right system, he likely could have continued along that path. As to right now, I don't know how ready he would be as it has been a few years.
