Someone already noted we aren't just talking about making the SEC game or playoffs, we're talking about winning the SEC championship and a national championship. There has been, so far, a consistent issue in 5 games now, against equal level talent teams in the RZ. Washington, Georgia 1 and 2, OSU 1 and 2 with 2 different QBs that were 5 stars and 1 of which was drafted to the NFL. It was also seen against lower level teams on occasion, like aggie so it isn't limited data against only top teams. The QBs were not the only offensive talent drafted and it was accompanied by some of the best defenses Texas has had in it's history.
Further, this RZ issue and Sarks unwillingness to take what the defense will give him has been commented on at multiple stages by multiple media sources.
To continue not to recognize it as an issue is either willful ignorance or lack of understanding fundamental aspects of offensive game planning.
