TCU Horned Frogs will be without starting quarterback Casey Pachall being suspended indefinitely for being arrested on a DWI. This is a huge blow for the No. 15 ranked team in the country, and their expectations have to be tempered quite a bit as the Horned Frogs will be rolling out Trevone Boykin against Iowa State this weekend.

Head coach Gary Patterson is not sure how long that Pachall will be out, and with the uncertainty SB Nation's TCU blog, Frogs O' War discusses what it means for their upcoming game against Iowa State. Plus they discuss how it will affect the team if Pachall is out for the entire season.

The entire Frogs O' War staff feel that the defense can lead them to victory over Iowa State this weekend, but it will be closer than expected without Pachall running the show. They also feel that Boykin will be running the ball a lot more since he is a better runner than Pachall. The Iowa State game is met with cautious optimism.

As for the rest of the season things are much more grim and

It's not going to be news that I think TCU was going to be underdogs most of the rest of the way. Pachall was going to read the defenses better than Boykin this season, and we'll miss that. But the win-loss totals may not show the difference; TCU has been setting itself up to lose plenty of games in 2012, with or without Pachall. What is going to change is the reasons people come up with for the losses. Aviante Collins and Big V and the o-line aren't going to be the scapegoats now; they going to be co-scapegoats with Boykin.

Every time the redshirt freshman throws an interception or keeps the ball too long and takes a sack, we're going to hear, "Pachall would have gotten rid of it in that situation." And sometimes that will be true; but not always.

Iowa State is a nice ice-breaker for Boykin earning his first college start, but after that the schedule gets exponentially tougher. TCU still has to go on the road to face Baylor, Oklahoma State, West Virginia and Texas. Then they still play Oklahoma and Kansas State at home, so a difficult second half of the season. This season is not likely to be planning out as expected for TCU now that Pachall is out.
