The Oklahoman's OU football and basketball beat writer Jake Trotter answered questions from readers in today's Power Lunch chat. Read the entire chat recap here. Participate in our Power Lunch chats Monday-Friday at 11 a.m. at NewsOK.com/sports On whether QB Drew Allen could adequately replace Landry Jones in an emergency: Big dropoff. Landry is one of the five best QBs in the country. Allen has never played a meaningful snap. Most teams see a dropoff when their backup goes on the field. On the other Top 5 quarterbacks in the nation: Brandon Weeden, Andrew Luck, Matt Barkley, Terrelle Pryor... that's off the top of my head (oops, forgot about Kellen Moore). On whether the offensive line is a cause for concern for the Sooners: Here's the deal with the line. If you don't have a bunch of high draft picks, the next best thing is experience. OU doesn't have a bunch of high draft picks, but this line does experience. 81 career starts, if you count Jarvis Jones (67 if you don't). I think that experience helps make this unit better. On walk-on running back Dominique Whaley: Spring game superstar. I'm not buying he makes the rotation until I actually see him get on the field in a game. Remember, Whaley had a big performance in the 2010 spring game, then never got a carry in the fall. On the impact of the early season matchup with Florida State: Big game. GameDay will be there. But yes, if Sooners lose, they will still be in the nat'l title picture. Just no margin for error after that.
