In this week's Big 12 roundtable, we break down position groups, which we've been ranking over the last two weeks:

Most improved position group?

Brandon Chatmon: I’m going with Kansas State’s receiving corps. And not just because of the spring emergence of Byron Pringle. If the junior college transfer can slide into the No. 1 receiver spot, K-State has some receivers that look like they may become quality complementary targets. Isaiah Zuber, Dominique Heath and Zach Reuter are some young receivers I really like who could excel in a complementary role.

Jake Trotter: How about the Texas quarterbacks? True freshman Shane Buechele was terrific in the spring game, and has already slightly changed the outside outlook for Texas for the 2016 season. He still has to win the job. But he's given the Longhorns a reason to be optimistic that quarterback could finally begin to be a strength again in Austin.

Position group that took biggest step backward or stagnated in the spring?

Chatmon: It has to be Texas Tech’s linebacking corps. Dakota Allen’s dismissal means a true freshman is next man up at linebacker. Johnathan Picone could be ready for the burden but that is asking a lot of an early enrollee to replace the Big 12’s sixth-leading returning tackler. Second-year coordinator David Gibbs’ job of rebuilding the Red Raider defense just got a little bit harder.

Trotter: I don't think they necessarily took a step backward, but the Oklahoma State running backs and offensive line didn't exactly pop in the spring game. Mike Gundy was adamant that the line and the running game had made progress over the spring. Maybe they did. But Oklahoma State is going to have to show more on the ground than it did in the spring game to be a Big 12 title contender this season. Maybe Stanford transfer Barry J. Sanders can give the Pokes a jolt.
