Johnny Manziel

Manziel struggled mightily in 2014, beaten out by Brian Hoyer in training camp and losing his only two starts. In about six quarters as a starter, Manziel completed 13-of-26 passes for 112 yards (4.31 YPA) and a 0:2 TD:INT ratio while adding just 16 yards on the ground (2.3 YPC). Then the tumultuous offseason began. The 2012 Heisman Trophy winner spent about 10 weeks in rehab after checking himself in Jan. 28. Manziel is expected to attend all OTAs, but based on offensive tackle Joe Thomas' comments, regaining the trust and respect of his teammates and coaches will be a tall order. His questionable work ethic has been well-documented dating to college, and it became painfully clear last season that Manziel isn't athletic enough (4.68 40) to get by on raw talent. What made Johnny Football special at Texas A&M was his ability to break the pocket and make improvisational plays, either throwing on the move or picking up yardage with his legs. But as he learned last season, those windows close much quicker in the NFL. Manziel will continue to struggle if he can't improve as a pocket passer, a task hindered by his height and receiver group (Dwayne Bowe, Brian Hartline, Andrew Hawkins). Josh McCown, who signed a three-year deal this offseason, is the favorite to start.
