Browns soon found how much of a learning curve a college spread QB like Manziel has. Play calls were tough. Snaps under center. Protections.

#Browns playbook was 1st Manziel used. A&M didn't use one. Battle was "Me vs the playbook." Players knew when he struggled to call the play

On Wednesday, the Browns named Brian Hoyer their starting quarterback. Coach Mike Pettine did not question Manziel's dedication and said he was pleased with his progress.

“He’s certainly made great strides,” Pettine said. “We are pleased with where he is, and he has shown that he has come a long way in his ability to pick up the playbook, be coachable and lead an offense. We are confident that Johnny is going to have a great future, but we just felt that Brian still had a decided edge on him.”

Pettine said last week, however, that was unsure if he would make a "permanent commitment" to either quarterback.

In Monday night's preseason game against Washington, Manziel completed 7-of-16 passes for 65 yards. He completed 7-of-11 passes for 63 yards in the Browns' preseason opener against Detroit.

Cleveland selected Manziel with the No. 22 pick in this year's draft. The 21-year-old won the Heisman Trophy in his redshirt freshman season with the Aggies in 2012.

The Browns went 4-12 and finished in last place in the AFC North last season.
