Johnny Manziel realizes that his height -- or lack thereof -- could become a point of concern for NFL executives as the draft combine approaches.

But Manziel cites Russell Wilson's recent success as proof that shorter quarterbacks can thrive in the NFL.

"I think he's kicked the door wide open," the 6-foot Manziel told the Houston Chronicle. "You're seeing more guys being successful avoiding that first wave of pressure -- get out and do things outside the pocket."

Wilson, who stands 5-11, helped lead the Seattle Seahawks to a blowout victory over the Denver Broncos two weeks ago in the Super Bowl.

A third-round draft selection in 2012, Wilson has thrown for more than 3,100 yards and 26 touchdown passes in each of his first two seasons with Seattle.

"Wilson does some things he's not asked to do when things don't go exactly as scripted," Manziel told the Chronicle. "He's able to extend the play.

"One reason they were so successful early in the Super Bowl was that he was 4-of-5 on third down and was able to continue to push the ball down the field and get them where they needed to be."
