Carr has never had an O-line, but people thought it would toughen him up and make him better, but it has made him turn into a deer in the headlights in a lot of situations. He has never grown into the QB people kept saying he would. After 5 years, you have to deliver no matter how bad the team is. Dude has never averaged more than 7.58 yards per completion. He has had more turnovers than TDs in every year in the league. He had more INTs than TDs in 06. He had 16 fumbles this year. Need I say more? Noone can realistically say he is a good QB anymore. Of course, with that said, I have no clue why they want to sign Plummer to replace him. Plummer is just as much of a turnover machine as Carr.
