Roundtable: Previewing TCU, OU, Iowa State spring games

In this week's Big 12 roundtable, we preview the three spring games that will be held this weekend:

What will you be focused on most in TCU's spring game?

Brandon Chatmon: The Horned Frogs' quarterbacks have to take center stage in TCU's spring game. Trevone Boykin will sit this one out so Bram Kohlhausen, Foster Sawyer and Grayson Muehlstein will get the chance to show they can run the offense. TCU was fortunate to be one of two Big 12 teams (Kansas State the other) that started the same quarterback in every game in 2014. The Horned Frogs need to find a quality backup to Boykin and one of those three could show he may be the answer on Friday night.

Max Olson: What is Gary Patterson going to do with his linebackers? I don't think it's a stretch to say that's a pretty important issue for TCU going into the fall. I like Sammy Douglas and figured Ty Summers would step up into a starting role, but he's reportedly been passed by true freshman Mike Freeze. Patterson says he doesn't have any true first-string linebackers right now, so that's certainly worth watching.

Jake Trotter: These new uniforms they're unveiling? Honestly, that might be the most exciting part of this spring game. With so many key players like Boykin sitting out, it's going to be difficult to get much of a read on the Horned Frogs. I am, though, interested to see how the new cornerbacks such as Torrance Mosley and Corry O'Meally do; Patterson has been high on their development this spring.

What will you be focused on most in Oklahoma's spring game?

Chatmon: I can't wait to see the impact of Lincoln Riley on the Sooners' offense. There's no doubt the offense will be vanilla in the spring game, but we should be able to see the subtle changes OU's new offensive coordinator has made to the mindset. And we should see that from the quarterbacks and receivers, the two positions that let the offense down in 2014. DeDe Westbrook, Mark Andrews and Dallis Todd are just a few of the receivers to keep an eye on this weekend. Riley's offense will create opportunities, but does OU have the talent on the roster to take advantage of those opportunities?

Olson: Baker Mayfield put on a show in his Oklahoma debut during last year's spring game. Can he do it again? Seems like the growing consensus around the conference lately is Mayfield is going to be the guy for the Sooners, but how quickly can he wrap this race up? I'm interested to see how he and Trevor Knight handle the pressure.

Trotter: All eyes will be on Mayfield for obvious reasons. Despite having never played a down at Oklahoma yet, he has emerged as the favorite to start at quarterback in the fall. How will he respond? Another big performance in the spring game (he was 10 of 10 passing last year) could give him a huge boost heading into August.

What will you be focused on most in Iowa State's spring game?

Chatmon: Mark Mangino wants the Cyclones' offense to become more physical and add a running game to the equation after ISU averaged 3.7 yards per carry in 2014. The Cyclones should be more familiar with Mangino's coaching and Saturday's spring game should be the first opportunity to show they will be improved. If not, ISU's hopes of a return to a bowl game could take a major hit.

Olson: The Cyclones' trio of wide receivers. Allen Lazard, D'Vario Montgomery and Quenton Bundrage are evoking understandable excitement in Ames this spring and should challenge opposing Big 12 secondaries this fall. We won't get to see Bundrage in the spring game -- he's still going non-contact as he recovers from a torn ACL -- but let's see just how big a leap Lazard and Montgomery have made.

Trotter: I'll be looking at what Mike Warren does in his public debut as a Cyclone. Warren went a little bit under the radar during his recruiting despite putting up monster numbers in Lawton, Oklahoma. He seems to have the all-around skill set that would make him a good fit as Iowa State's featured back, which the Cyclones need following the unexpected departure of DeVondrick Nealy.
