In today's Twitter mailbag, we discuss the Oklahoma stadium renovation, the gap between TCU, Baylor and the rest of the conference and what could happen around the league in the days leading up to signing day.

On to the 'bag:

@Jake_Trotter what is the story with the OU stadium expansion, on, scaled back, off, on again?

— James Aydelott (@jamesaydelott) January 29, 2015

Trotter: James, of course, is referring to the report Wednesday that Oklahoma had delayed its stadium renovation plans, which president David Boren later vehemently denied. I have spoken to a couple of people about this and here's what I can say: The school has in fact endured fundraising issues, due in small part to the mediocre football season and due in large part to falling oil prices. (Oklahoma's economy, and thus donor base, is significantly tied to energy.) I have also heard rumblings that the school might ultimately scale back some of the original proposal, which at $370 million was ambitious to begin with. But as far as I know, the school has no plans to delay construction. In fact, I don't believe Boren has the authority to call off or delay construction without approval of the regents first. The regents did not discuss the stadium proposal in their meeting Wednesday, but you can bet they will be discussing it informally in the coming weeks before formally hashing out the next step at its scheduled March meeting in Tulsa.

@Jake_Trotter who do you think will be wvu qb next year ?

Trotter: My money is on William Crest. I know Skylar Howard had some moments filling in for Clint Trickett last season. But there was a reason why Crest as a true freshman beat out Howard as the No. 2 quarterback coming out of August before suffering a shoulder injury. Howard's mobility added another dimension to the West Virginia offense. But he really struggled with his accuracy at times. Based on what I've heard about Crest and his potential, I think he's West Virginia's long-term answer behind center.

@Jake_Trotter will there be a huge gap between baylor/tcu and the rest of the conference?

— Isaac (@haas_isaac) January 29, 2015

Trotter: I think so. Of course, we thought there would be a huge gap between Baylor/Oklahoma and rest of the conference this season. Then the Sooners finished 8-5. A lot can happen. Baylor could encounter issues replacing Bryce Petty at quarterback. TCU could struggle with new faces defensively. There could also be a surprise team come out of nowhere, just like TCU this past season. But with what the two teams have coming back, there's a lot more to like about TCU and Baylor right now than anyone else in the conference.

@Jake_Trotter Chris Warren, Chris Carson, Jordan Stevenson, other. Rank them on the likelihood each winds up in Stillwater. And Devin Davis?

Trotter: Jordan Stevenson seems most likely, followed by Chris Carson, then Chris Warren III. But my educated guess is that none of three you mentioned will end up in Stillwater. That doesn't mean Oklahoma State won't land a high-profile running back. I just get the sense the Pokes are targeting a late flip from somewhere else, maybe. As for Devin Davis, I don't know that he's ever going to get over that devastating knee injury. That would be too bad, too, because people were talking about him as a potential first-round talent as a left tackle.

@Jake_Trotter Who do you think is bringing in the strongest recruiting class ? and whose class will make an impact this year ?

— E (@Vandeezal) January 29, 2015

Trotter: Texas is putting together the most impressive recruiting class, though the Longhorns are taking quite a gamble. If they don't flip Kyler Murray from Texas A&M, they could whiff on signing a quarterback, which was the probably the biggest need in this class. Just about every class is going to have some impact in 2015, although Texas has some major pieces graduating. Considering the caliber of players the Longhorns are bringing in - and could bring in - the answer could be them also.

@Jake_Trotter is TCU still the frontrunner for Daylon Mack? how important is Kyler Murray's decision?

— Steve Godich (@_CaptainCowboy) January 29, 2015

Trotter: I have no idea who Mack's front-runner is anymore. He canceled an unofficial visit to TCU this weekend, which isn't a great sign for the Horned Frogs. Of course, it doesn't rule them out, either. But there seems to be some Texas momentum with Mack. Murray, again, is huge for the Longhorns. It's the difference between them possibly having their quarterback of the future and the status quo, which wasn't great for them last year.

@Jake_Trotter how do you see Texas Tech finishing up in their race for some last-minute top recruits?

— Jeremy Fry (@jeremy_fry) January 29, 2015

Trotter: Tech is hoping to land ESPN 300 defensive tackle Darrion Daniels and/or ESPN 300 RB Chris Warren III. I don't feel great about their chances for either, though we'll see what happens. Daniels is expected to announce between Texas Tech, Iowa, Oklahoma and Oklahoma State on Friday night. Warren seems like he's leaning toward either Washington or Texas. The Red Raiders are also still in on ESPN 300 defensive tackle Joseph Wicker, who is down to Arizona State, UCLA and Texas Tech, as well as three-star New Orleans linebacker Arthur McGinnis. If they can land one of Daniels, Wicker or McGinnis - and they can prevent any more decommitments - it will be a solid finish to a very solid class.

@Jake_Trotter What under-the-radar Big 12 commits do you expect to have an immediate impact?

— Forrest Grimes (@FGrimesN7) January 29, 2015

Trotter: I like K-State running back commit Alex Barnes, who is just a three-star prospect. Bill Snyder doesn't like to play freshmen, either, but Barnes has the size to help a backfield in need of help right away. Another underrated guy I think could be a factor next season is Oklahoma three-star cornerback Antoine Stephens. The Sooners desperately need CB reinforcements. And even though Stephens went under the radar with his recruitment, he has the size and range that Mike Stoops covets in his cornerbacks.

@Jake_Trotter which is the generally more frustrating human: Julie Taylor of Friday Night Lights or a Baylor fan?

— Luke (@lehockett) January 29, 2015

Trotter: I've never seen "Friday Night Lights" and I love Baylor fans. I'm just not sure they love me back.
