Four wins. That is what Gary Patterson and his Texas Christian University Horned Frogs mustered in 2013, taking a major step back from being a conference buster in the BCS. Now with new aspirations for a more competitive 2014, what does Patterson have in store for his school and the other 127 football programs?

In a preview by Athlon Sports, TCU’s defense was solid last season, the offense was a disaster, finishing near the bottom of the FBS ranks in both total and rushing yards.  Not surprisingly, Patterson made some changes on his coaching staff, bringing in two new coordinators to overhaul the offense. This will be the key for the Horned Frogs’ hopes this fall, as the defense returns eight starters and could be one of the better units not only in the Big 12, but the entire nation.

And if that is not enough to be concerned about, here are five more questions that need to be answered in 2014.

How will the offense look?

Things were so bad on that side of the ball that despite being a top 25 defense nationally, TCU managed just four wins, one of them coming against an FCS opponent. And the other three victories were over Kansas, Iowa State and SMU, teams that went a combined 11-25. Not surprisingly, head coach Gary Patterson made some changes in the offseason, bringing in two new offensive coordinators to hopefully “fix” his offense. Doug Meacham comes to TCU after spending last season as the offensive coordinator at Houston. Sonny Cumbie joins the Horned Frogs’ staff after serving as the quarterbacks coach and co-offensive coordinator at fellow Big 12 member Texas Tech.

Who will throw the ball?

Despite having two experienced signal-callers last season, the tandem of Casey Pachall and Trevone Boykin produced disappointing results. With both seeing plenty of action, the duo combined to complete 57.1 percent of their passes for 2,666 yards while throwing more interceptions (17) than touchdowns (13). Pachall has exhausted his eligibility, leaving Boykin, a junior, atop the depth chart entering spring practice, at least for now. TCU also has sophomore Tyler Matthews and redshirt freshman Zach Allen who are expected to see plenty of reps this spring, as the Horned Frogs are shifting to more of a spread offensive system under new co-coordinators Doug Meacham and Sonny Cumbie.

Changing things up

There’s been some talk already that Boykin could be moved to wide receiver, which means Matthews and Allen should get plenty of opportunities to impress the coaching staff and potentially shake up the depth chart. Either way, expect plenty of attention to be paid to what happens under center this spring.

And on the defensive side of the ball…

TCU returns eight starters from a defense that finished in the top 25 in the nation in yards allowed. This unit should be the strength of this team, but that doesn’t mean that defensive coordinator Dick Bumpas can sit back and take it easy during spring practice. For one, he has some decisions to make regarding his secondary, which is made up of five defensive backs due to the unique 4-2-5 scheme the Horned Frogs have long employed under Patterson. The biggest loss from last season is cornerback Jason Verrett, who earned first-team All-Big 12 honors after leading the conference in passes broken up (14) while recording two interceptions.

A strong secondary …

The secondary should be in good shape with senior strong safety Sam Carter, senior cornerback Kevin White and junior wide safety Chris Hackett forming a strong foundation to build around. However, Bumpas will need someone new to step up at cornerback opposite White and in the free safety spot that was occupied by Elisha Olabode last season. Otherwise, the front six returns largely intact form last year’s starting group, which doesn’t include Devonte Fields. The 2012 Big 12 Defensive Player of the Year as a true freshman, Fields played in just three games last season because of injury. He will start the spring second on the depth chart at right end.
