Senior James Dunbar knows this and it's been a driving point each week for them to improve.
Dunbar, a captain for the Frogs, has played guard and center this season but has supplanted himself as the starter at left tackle the last few ball games.
For Dunbar, he says it's a blessing to even be at TCU. Dunbar did not play for the Frogs in 2012 because he was academically ineligible. He returned in the spring of 2013 as a walk-on, paying his own tuition. After regaining his academic eligibility, he was placed on full scholarship again in the fall.
Dunbar credits his return and maturity to offensive line coach Eddie Williamson.
