You’re not wrong about Texas coaches, but after Mack and DKR there is a big drop off. If asked to support your ranking with just his Big 12 years i don’t think that he is better than Briles or Slocum.
Patterson has had one really good year in the Big 12 and a couple of good years like this one. Even his overall record is padded with very weak teams like Baylor’s always was. They have 2 gimme out of conference games a year that bigger programs like UT and OU don’t. Their non conference games were SMU, Jackson St, and Arkansas. In 2012 when that they were 12-1 they played Sanford, Minnesota, and SMU.
