I don't want Petrino replaced and I'm not expecting Louisville to beat Alabama or even come within 2 touchdowns of Alabama. What I would like is for at least 8-9 wins this year and for the program to take a big leap forward in 2019 and challenge for a playoff spot. 
I feel like I'm having to beat this horse to a pulp but people still keep reading my statements wrong. Petrino has done an admirable job, downright good job in his first 4 years...there have been concerning things that have occurred that would leave some to at least lose a little faith in him. That's all I was saying. His bowl record, his record vs ranked teams, his inability to find a quality DC, his inability to put together a decent defense, insane losses to UVA, UK, BC, absolute beat downs on national tv from Houston, Clemson, NC State, LSU, UGA...when you combine them all are all areas that should at least raise some slight concern as he adjusts to life in the ACC. 
What's his signature win or moment during Petrino 2.0? Beating the piss outta FSU .....and then what? Beating a 7 win Notre Dame team? 
My purpose was never to call for his head it was only to point out that if you take a step back and look at his body of work over the last 4 years he's beaten nearly all the teams he should have and lost nearly every big test he's faced so the idea that just because "he's doing pretty good" is enough to warrant being ridiculed for even bringing up replacing him is crazy.
