It can be done. Arkansas State had a blueprint (up until Blake Anderson wore out his welcome). App State has a blueprint and has held by it. UL can do the same.
Arkansas State went from Hugh Freeze to Gus Malzahn to Bryan Harsin to Blake Anderson and were 85-48 under those coaches in those years.
App State went from Scott Satterfield to Eli Drinkwitz to Shawn Clark and went 83-15 under those coaches in those years (Not to mention what they did with Sparky Woods and Jerry More before that which was a totla of 253-106-2.
It can be done, we just need to make it happen.
