Baltimore Ravens offensive coordinator Greg Roman isn't buying into the criticism of quarterbacks getting hurt while running.

"I think it's a little overrated, the whole danger thing," Roman said. "Why? Because, and this is empirical data here, over the years, you kind of realize that when a quarterback decides to run, he's in control. So now [if] he wants to slide, he can slide. If he wants to dive, he can dive, get out of bounds, all of those different things. He can get down, declare himself down.

"A lot of the time, the situations that [have] more danger are when he doesn't see what's coming -- my eyes are downfield, I'm standing stationary from the pocket, somebody is hitting me from the blind side. My experience, and I kind of learned this, is that when the quarterback takes the ball and starts to run, there's not a lot of danger involved in that relative to other situations."

Roman has worked with mobile quarterbacks Alex Smith, Colin Kaepernick and Tyrod Taylor in the past.
