First things first, you have to give J.W. Walsh credit. He threw for over 400 yards on Saturday against one of the Big 12's best defenses.
Even more impressive? He apparently did it on a bum knee that will sideline him for the rest of the season, Gundy said on Sunday night. Walsh's father, Denton Guyer coach John Walsh, told two different media outlets that Walsh's knee injury wasn't season-ending, but unless Wes Lunt still can't play, it might as well be.
Any talk of a medical redshirt is over now. Oklahoma State may have to turn to third-string junior Clint Chelf this week, but Gundy sounded hopeful on Sunday that Lunt would be ready.
Walsh provided Gundy the ability to be patient without sacrificing a huge amount of production.
Who knows how Chelf would perform, but Gundy knows what he has when Lunt is healthy. Walsh's rise allowed Lunt to get back to 100 percent before Gundy needed him back on the field.
How close was Lunt to 100 percent last week? He's been practicing for a few weeks now, but Gundy's reluctance to talk injuries leaves plenty of doubt.
What's not doubtful anymore? With Walsh down, there's a new sense of urgency for Oklahoma State at quarterback.
TCU has a play-making defense that has already made 14 interceptions this season, tied for third most in FBS. The Cowboys will need good play from the quarterback spot to win that game, though the Frogs are banged up on both sides of the ball.
Can Chelf provide it?
Gundy may not want to run the risk of finding out.
