In today's Big 12 Twitter mailbag, we discuss why TCU was picked over Baylor in the preseason poll, whether Oklahoma running back Samaje Perine can make a run for the Heisman and where Texas coaches will be eating now that they have limited access to the school's dining hall. My head is still spinning from this week, which included Big 12 media days and the ESPN car wash. Nevertheless, we charge forward with the 'bag:

@Jake_Trotter Baylor has won the Big 12 twice and has lost hardly any starters, how come they aren't favored to win the conf again?

Trotter: Personally, I voted TCU over Baylor primarily for two reasons: quarterback and schedule. TCU has a proven QB in Trevone Boykin; Seth Russell is a relative unknown. And Baylor has to go to Fort Worth. Whenever teams are close, I always go back to quarterback and schedule. As a result, TCU got the edge, at least on my ballot.

@Jake_Trotter Who will get the start at QB for OU? Will he stay the starter all season or will it be QB by committee like last two years?

- CoachD (@CoachDedmon) July 24, 2015

Trotter: Oklahoma will be in major trouble if it falls into QB by committee again. Provided his shoulder is 100 percent, Baker Mayfield will, in my opinion, be the opening-day starter. How will he fare? I have no idea; after all, he hasn't played in two years. But the Sooners' Week 2 trip to Tennessee will tell us a lot about Mayfield's staying power. If he thrives, the Sooners will have their QB. If he struggles (and OU loses) it could be another long season in Norman.

@Jake_Trotter can OKLAHOMA Perine break his own record this season and make a play for the Heisman ?

Trotter: It will be tough. Since the turn of the millennium, only one running back (Mark Ingram in 2009) has won the Heisman. I do think that Perine could have a monster season. He rushed for 1,700 yards last year, and wasn't even the team's starting running back through September. Even in Lincoln Riley's air raid, I don't think 2,000 yards is out of the question. If Perine closes in on that milestone -- and Oklahoma is a factor nationally -- Perine will definitely be in the Heisman conversation.

@Jake_Trotter IF the Big 12 had a championship, what would happen if each power 5 conference had one undefeated team?

- Isaac (@haas_isaac) July 24, 2015

Trotter: It would depend on the teams in question, and also how each conference fared outside the league. Texas and Oklahoma would compare favorably because of their nonconference schedules. Baylor invariably would have problems because it would have the weakest nonconference schedule in pretty much any scenario. That's why the Bears have been scrambling to upgrade their nonconference slate in the short term, going so far as to try and play a game in Australia. They're beginning to realize what an albatross their out-of-conference schedule is in the minds of the playoff committee.

@Jake_Trotter @ESPN_Big12 could WVU see Crest develop as a threat at WR like Boykin did? He only weighs two pounds less now as a Freshman

- John Ashworth (@Poca_Ashworth) July 24, 2015

Trotter: William Crest is a big-time athlete. That's why Dana Holgorsen is going to give him a shot in a Wendell Smallwood-like role. With Crest, I wonder if in fact Holgorsen has Boykin in the back of his mind; Holgorsen was always complimentary of Boykin's receiving skills. Who knows at this point how the transition will work for Crest. But the skill set comparison, I think, is a fair one.

@Jake_Trotter favorite quote by Briles at Big 12 Media Day?

- Matt McBrayer (@McBeezy) July 24, 2015

Trotter: "You give me somebody to develop and they're going to be hugging Pete Rozelle or whoever's the NFL commissioner now. Is that who it is? Who is it?"

@Jake_Trotter more likely to happen first: B12 expansion or playoff expansion?

- Hammer (@ImaHammerU) July 24, 2015

Trotter: I would bet on Big 12 expansion. It takes college football the sport forever to change anything. Case in point: How long have we been talking about implementing an early signing day? It feels like forever. Remember, it took like 25 years of confabulation before we finally actually got a playoff. At the moment, Big 12 expansion seems to have more momentum than playoff expansion.

@Jake_Trotter rank your top 10 WR's in the conference.

- E (@Vandeezal) July 24, 2015

Trotter: Corey Coleman, Sterling Shepard, Josh Doctson, KD Cannon, Brandon Sheperd, Kolby Listenbee, Allen Lazard, James Washington, Devin Lauderdale and Dede Westbrook.

@Jake_Trotter when Cincinnati is invited to the big 12; what will you try first? Montgomery Inn ribs or Greater's Ice Cream?

- Herr änder (@CincyGuy2009) July 24, 2015

Trotter: I would be all for adding the Bearcats, for selfish reasons (my first job out of college was in Middletown, Ohio, and my wife is from Southwest Ohio). As much as I love Graeter's (black raspberry chocolate chip) and the Montgomery Inn (rack of ribs with onion straws), my first stop would be to Skyline Chili (three loaded cheese coneys with hot sauce).

@Jake_Trotter What's your UT Campus-area lunch pick for Longhorn coaches now that they can't eat for free at the cafeteria

- sully (@skippable) July 24, 2015

Trotter: Maybe the Texas coaches can work out a deal with Franklin's to get in there without waiting in line. Briefly I got to talk Austin BBQ with Charlie Strong during the car wash, and he noted JMueller BBQ had become one of his favorite stops. Really, the silver lining in all this is, if you're going to get bounced from a dining hall, what better city to have it happen in than Austin? Culinarily, New York City. And that's it.
