The Oklahoman's OU men's basketball beat writer Mike Baldwin 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 OU defensive end Ronnell Lewis can be an All-American: All-American is setting the bar way too high for a guy that was converting from linebacker to defensive end at this time last season. All conference is probably even too lofty. Lewis has good potential but his best attribute so far has been on big-time hits on kickoff coverage. On how OU's offense will change without coordinator Kevin Wilson: Everyone says the changes will be subtle, that Josh Heupel will essentially call the same type of plays. There has to be some differences but remember Landry Jones led the nation in pass attempts last year. Wilson threw the ball more than people think. On the OU-Texas game: OU is currently a 8-point favorite but let's wait and see if Texas is vastly improved. The Sooners will be heavy favorites. Texas could go around 7-5 and 8-4 but might be better than people project if they get decent QB play and the freshman RB is as good as advertised. But those are big ifs in August. On which school has the better defense - OU or OSU: OU should have the better defense. The Sooners have a lot more experience returning and higher rated recruits. If OSU ever assembled a top 30 type of defense the Cowboys would definitely contend for Big 12 titles, possibly more. I'm not saying OSU's defense will be horrible. But that is the Cowboys biggest question mark heading into fall camp.
