I might add to this as the post-James, points when it was clear the coaches weren't the guys and it was time to make moves to move on because I believe that was what happened Saturday.
Lambright - 1994 after the Apple Cup. Sidenote: Lambo went 9-7 in-conference in his first two seasons in a very down Pac-10 with the talent on those teams. It was obvious he was not the guy but also it was a different era I guess too where it took a lot to fire coaches..
Neuheisel - 2002 Cal - Have to remember how big of a deal losing to Cal, especially at home was at that time and that the team was ranked #12 at the time. You don't fire him there but I think a case could have been made after the Sun Bowl. Had Neuheisel not gotten himself fired off the field, I think he would have tanked in 2003 and gotten fired.
Gilby - 2003 Nevada - It was already pretty obvious looking back after how horribly they got thrashed the week before by an average UCLA team. Give him the rest of the year but look for a coach at that point. Losing to an Arizona team that was 2006-Stanford level bad and losing to an above average Cal team 54-7 pile onto that.
Willingham - 2005 Air Force - What an abomination of an opening game. Obviously you can't fire him at this point but it was clear he was a mess. 2006 suddenly senior loss to Stanford and 2007 Apple Cup were when you could actually fire him.
Sark - 2012 at Arizona - Getting absolutely blown out by an above average at best Arizona team confirmed to me Sark was never going to turn the corner. Then losing the Apple Cup after building up the chance to get some momentum going into a make or break year doubled that up. To Sark's credit I never thought he did enough to deserve to get fired on the field though I think he would have went 8-6 too in 2014 and finally would.
Petersen - 2019 Cal - Never thought Petersen wasn't the guy, but losing to Cal, two years in a row, at home, and only scoring 19, with the talent this team had and an NFL-skilled QB cemented to me that something was really wrong with Petersen. At Stanford and at Colorado continue that. Damn, that team was so close to getting an easy 10-11-win season.
Lake - John Donovan hire. Looking back that was so much more than a red flag. It was a white flag. [/b]
