At first I thought the same...wow look at those yards, in less games more yardage. But then I see Jackson threw the ball more but had a worse completion %, fewer tds, and more picks (almost double). You would expect that with the yardage he would have more tds but he doesn't. McCarron also only lost 4 games his entire career. Though it gives him credit for 4 years he was only a 3 year starter. To me if the Bills draft Jackson they'll get a guy that turns the ball over more and is inaccurate with his throws. I don't see him as good as Deshaun Watson. Watson is on another level.
Also have to remember that A.J. got the Bengals to the playoffs and had them ahead until a fumble by the r.b. in the closing minutes and personal fouls by the morons in the defensive back field. Who by the way I would have released after the game after their bonehead plays.
Really a tough call on who to draft. I watch a lot of college ball and each one of these qbs have issues and will need to sit for awhile to adjust. I wouldn't want to be a GM this year.
