Picasso couldn't paint masterpieces with tools made out of ****. Fitzpatrick has serious physical limitations, which were on display before he got here and have continued at both stops since he left. He is what he is.
I don't know if Geno Smith has the mental acuity and drive to be an elite NFL QB. He certainly has the physical skill set but if he doesn't have the "want to", no one will get it out of him.
