Brian Billick rips Johnny Manziel's chances of surviving in NFL
Manziel recently completed his rookie season with the Cleveland Browns. The quarterback started two games late in the season before sustaining an injury that put him on injured reserve.
"I've seen absolutely nothing in demeanor or skill set to indicate Johnny Manziel has any chance of surviving in this game," said Billick.
The 22-year-old lost a preseason quarterback battle with veteran Brian Hoyer in August. Manziel threw for 175 yards, two interceptions and one rushing touchdown in his limited play in 2014.
After an ESPN.com story last week quoted an anonymous Browns player as saying the rookie quarterback thought the entire season was a "100 percent joke," Browns players Karlos Dansby and Joe Haden defended Manziel on Wednesday.
"Rookie seasons, they go however, but I think Johnny really understands what he needs to do to be successful," Haden said.
Manziel won the Heisman Trophy while at Texas A&M after throwing for 3,706 yards and 26 touchdowns and rushing for another 1,410 yards and 21 touchdowns in 2012.
Billick was the Baltimore Ravens head coach from 1999-2007.
