Could Bryn Renner be the Ravens' backup quarterback? Posted Aug 26, 2015 I seriously doubt the Ravens keep three quarterbacks on the roster. That means that either Matt Schaub or Bryn Renner will take a seat behind ironman quarterback Joe Flacco. Almost everyone has expected that Schaub would be the guy to hold the clipboard, but Renner is making that decision a little harder. You know Renner for his great two-minute drill against the Saints where he ran the ball in for a score with seconds left on the clock to beat the new Orleans Saints at home. (Baltimore Beatdown)
