Briles has inherited two bad situations.
He took over at Houston after the dumpster fire our current OC left behind and played a non-conference schedule that Snyder would have dropped like a plate of whipped butter or changed faster than moving the team to the shady side of the plane on a trans-continental flight through multiple time zones (Oregon, Alabama, Michigan, Miss. State, Oklahoma State and Miami). With TCU, Louisville, Southern Miss (when they were good), Central Florida (thank you again EMAW sniper) and East Carolina on the conference schedule in the first 2-3 years, and did well.
Then walked into another dumpster fire at Baylor playing against a Big 12 South schedule and 4 BCS school non-conference games in his first 2 years.
