There have been a few QB's who washed out on their first stop or couldn't get on the field due to personality issues who turned out to be great the second place. I doubt Manziel will join that club but the Falcons definitely thought Favre was a nobody when they traded him.
http://www.businessinsider.com/john...he-browns-this-week-against-the-49ers-2015-12 Johnny Manziel's two-week timeout for his off-field behavior appears to be over as he is now in line to start the final four weeks of the season for the Cleveland Browns after being benched. Chris Mortensen of ESPN reports that a source told him Manziel will replace Austin Davis as the starting quarterback "unless Manziel had done something to jeopardize his status between the end of Sunday's loss and Monday."
