I was just telling someone this same thing. Jaimes is quietly having a very good season. He's strong and his technique is good. When Farmer plays center we look fine at center, left guard, and left tackle. IMHO Foster & Farniok lack a little bit of strength and just get pushed around a bit and then hold in order to protect Martinez.
Our tackles have been odd this year. Against Colorado Farniok struggled. Then against Troy, Jaimes had a terrible game. Now it's flipped back to Jaimes being solid and Farniok struggling.
