Troubled former NFL quarterback Johnny Manziel is trying to work his way back into the NFL. After being caught up hard in the party life, the 25 year old has cleaned up his act and is trying to work his way back. A couple of days ago Manziel threw some passes at University of San Diego's pro day. The former first round pick had 14 teams in attendance to watch him and one of those teams was the Chicago Bears. Manziel was close to signing a deal with the CFL's Hamilton Tiger-Cats but apparently walked away from the deal due to some details. The former Heisman trophy winner would definitely be a project, however it's likely nobody wants Manziel anywhere near Mitch Trubisky. On the other hand, if Manziel is fully clean, he could have a thing or two to teach Trubisky about what not to do in his young NFL career. The Browns, Chargers, Giants, Chiefs, Jets, Patriots, Raiders, Titans, Lions, Jaguars, Panthers and Buccaneers were also in attendance.
