Left tackle Donald Stephenson—At 6-foot-6, 285 lb., Stephenson is listed as the second smallest on the offensive line, but he has especially impressed this spring with his athleticism.
Left guard Stephen Good—Good suffered the only notable injury in the Spring Game, but it turned out to be only a mild ankle sprain. So, he should be back and well by the fall to help solidify the left side of the line.
Center Ben Habern—Habern was forced to the sidelines for the remainder of 2009 after breaking his fibula in a game at Texas Tech. But he is back and healthy and participated much more extensively in the spring than previously anticipated, so that's encouraging.
Right guard Tyler Evans—Evans is the only underclassman on the current starting depth chart, but he has certainly showed some progress as well, claiming to have put a focus of emphasis on taking care of the "small things" in his O-line game.
Right tackle Cory Brandon—Fans certainly cringe at the thoughts of the BYU game last year when Brandon's flurry of false starts were costly in an upset loss, but if the reports are true—granted live game situations aren't able to be simulated in the offseason—the entire line, including Brandon, has grown more mentally tough and these errors have started to subside.
Something the coaches and players alike talked about during the spring was the increased depth at the offensive line position thanks to all the injuries the Sooners did, in fact, deal with last season. And this shows up with the reserve guys, including left tackle Jarvis Jones, left tackle Bronson Irwin, center Gabe Ikard, right guard Tavaris Jeffries, and right tackle Josh Aladenoye. All of those guys have made improvements, but there are still some ifs about the starters and reserves alike until the season gets going.
1. In great shape
2. Probably in good shape
4. Not in good shape at all
