He isn't good, nor even average, I'm not saying that,.
He is a mediocre QB in which the Bills need to improve on, but he is still better than some starting QBS in this league.
Unless you think some QBS like Bortlers, Cutler,Trubisky, Kizer, Siemian are better than him.
I think you should be the one to take off the blinders if you think those QBS are better than Tyrod right now
