He's a long way from being fired and it would never happen this season even if we did go 3-9, for example. He has done a very good job getting the program back to prominence. Additionally, by all accounts he has built a strong culture focused on building high character guys. I think he looks for high character guys when recruiting. O'Brien did a very good job and held the program together so it is not like when he took over in 2014 we were horrible. Yes, the talent level was down and the depth was very low but we had talent. I would argue the brand was still good and he inherited a decent program.
He has gotten us all the way back to very good and top 10 status but not elite.....yet.
With that said he is not untouchable. This game is still about wins and losses even at Penn State.
He would need to hit a pretty bad dry spell to get fired without cause. Probably some kind of mediocre run over 5 plus seasons where we lose 4 or more games every year, of course don't make the playoffs and slip into irrelevance on the national scene. At that point, if it would ever happen, and we are a mediocre B10 team with no sign of improving then I would imagine a change would be made. This also would assume his buy out would be reasonable.
