Casey Pachall's successful return to TCU will rely heavily on the play of his offensive line.
The TCU Horned Frogs have high hopes in 2013. With QB Casey Pachall returning to the team and one of the best defenses, Gary Patterson could have his team competing for a Big 12 title.
However, the biggest issue Patterson will have to address is the offensive line.
Losing interior lineman James Fry and Blaize Foltz was a big blow to the Horned Frogs this offseason, and replacing them is a big task for Patterson.
Last season, the Horned Frogs allowed 29 sacks, the most in the Big 12. That also put TCU at 83rd nationally in sacks given up. However, that problem had more to do with the play of inexperienced quarterback Trevone Boykin.
In four games last year, Pachall was only sacked three times. That meant in the last 10 games for TCU, Boykin allowed himself to be taken down 26 times.
Jamelle Naff is projected to replace Foltz, according to ESPN's David Ubben. Eric Tausch and Joey Hunt will also play big roles on the line in 2013.
While the Horned Frogs offensive line lacks depth heading into the season, if they can be as successful as they were early in the year in 2012, they could be just good enough to allow Pachall and company to propel TCU to a title in 2013.
