Big 12 mailbag: TCU in line to surprise?

In this week's Big 12 Twitter mailbag, we discuss surprise team possibilities, the potential of second-year players around the conference and the best dessert spot in the league.

On to the 'bag:

Trotter: You know, we did our position rankings these last two weeks, and TCU stunningly had the highest average position, well ahead of both Oklahoma schools. Maybe as a whole we're undervaluing the Horned Frogs. They really have no glaring weaknesses, relative to the rest of the conference. If Kenny Hill can find consistency and avoid negative plays and turnovers, perhaps TCU could contend.

Trotter: After Baker Mayfield and Mason Rudolph, who are the clear top two, there's a debate for third. I would be fairly stunned if that wound up being Jacob Park, especially given Iowa State's propensity to seemingly annually switch quarterbacks. But I just mentioned Hill's uneven performance last season. Jesse Ertz has been prone to injury. Will Grier hasn't played in two seasons. I'm not convinced Shane Buechele will hold on to this starting job. And Texas Tech and Baylor could have transfer starters. Park definitely played well down the stretch last season. So there's a window for upward mobility in the conference quarterback pecking order.

Trotter: Mayfield has been in the top five of the voting the past two seasons. So he's the obvious Big 12 favorite.

Trotter: Rodney Anderson is coming off two significant season-ending injuries, and Abdul Adams didn't show much in limited opportunities last season. So the position is wide open. I think Trey Sermon has a terrific chance of winning the starting job, maybe an even better chance than Marcelias Sutton, who seems like more of a change-of-pace option than an every-down back.

Trotter: Oklahoma linebacker Caleb Kelly, Oklahoma State linebacker Calvin Bundage (still working on where to be, but he can strike), Kansas State running back Alex Barnes (I realize he was a redshirt freshman), Kansas safety Mike Lee, Texas receiver Devin Duvernay (if they finally throw him the ball), Texas DE/OLB Malcolm Roach and Texas Tech linebacker Jordyn Brooks (the Red Raiders have a lot of hopes riding on him him).

Trotter: I try not to eat much dessert on the road, but I usually swing by Varsity Donuts on my way out of Manhattan during the season. Great coffee. Phenomenal donuts, especially the pistachio.

Trotter: Understandable. You took an uppercut right to the chin.
