Good point. After 4 years playing a shotgun spread offense, his first 20+ games he doesn't look like Aaron Rodgers, or even Big Ben, we should give up on him. I agree. He had the month of December, a 5 week stretch, his rookie year where he was the highest rated QB after only Peyton Manning and after returning to the line-up after being benched last year he was the 7th ranked QB in the NFL...
...but it's been two season, cut him and move on. For those who feel this way, dont draft Mariota, who also spent years in a spread offense out of shotgun, because we'll need to cut him in 2 years also, because if Mariota had to go 2 season with Stephen Hill, Kerley, David Nelson, Jeff Cumberland, and Decker with a pulled hamstring...we'd have another failed developed QB and Mariota isn't likely to performe at a Manning's level like Geno did while playing with Cumberland, Nelson, Hill, and Kerley...which is what Geno was working with. Yep, cut the kid for outplaying Brady with those weapons. He's shown nothing. Good point.
