You can fire up the coaching carousel again today. Louisville has fired Bobby Petrino in the midst of a nightmare season.Just two years ago, the Cardinals cracked the top 10 and had the Heisman Trophy winner in Lamar Jackson. Now, they are 2-8 and have been playing progressively worse as the season has unfolded.With Petrino out of the picture, you don’t need any fancy coaching hot boards to figure out who Louisville will target to replace him. There is one obvious answer: Purdue’s Jeff Brohm.ESPN’s Kirk Herbstreit agrees. He named Brohm the No. 1 candidate a short time ago on Twitter.1st name obviously to come up will be former Louisville QB and current Purdue Head Coach Jeff Brohm. https://t.co/4Ex85qtkkc— Kirk Herbstreit (@KirkHerbstreit) November 11, 2018Brohm is an obvious candidate for a couple of reasons. First and foremost, he is a Louisville alum, having starred for the Cards in the early 1990s before a seven-year NFL career.Secondly, Brohm has a winning track record at Western Kentucky and Purdue. He is 42-21 in four-plus seasons as a head coach, and if the Boilermakers win one of their last two games, he’ll have reached a bowl in each of his first five campaigns.Brohm is also known as an offensive innovator, and you can see that in the way he turned around Purdue almost immediately. The Boilermakers used Brohm’s explosive and creative attack to throttle Ohio State in a massive upset earlier this season.Of course, there’s no guarantee that Louisville will hire Brohm. But the odds seem pretty good right now that they get it done.
