I see where you are coming from, but it's all relative.
Yes, CSU is currently a dumpster fire and Norvel was the head man that lead them there. But that CSU team is devoid of talent at pretty much every position. Norvel obviously messed up on the recruiting front, but if we separate recruiting from coaching, then I'd say it's a minor miracle that he got that team to beat Fresno State the way they did.
My main problem with Sawvel is that I feel like we have underperformed in relationship to the talent we have on the team. Are we the most talented team in the conference? No. But we have had enough talent on the team these last two years that we should not be losing at home to Idaho, or losing at home to a 1-7 Utah State team, or squeaking by a pretty bad Akron team, or needing a furious 4th quarter rally to beat a mediocre SJSU team at home, or losing to a 1-5 Air Force team. All these performances have happened in not even two full seasons. In my opinion, the dismantling of CSU this year or the road win against WSU last year don't make up for all of these flops.
Let me ask you this, if Sawvel was the head man at CSU this year, do you think CSU would have won any more than the 2 wins they have under Norvel? I don't. Honestly, I think he likely finds a way to lose both the Northern Colorado and Fresno State games. Obviously, we will never know, but I'm curious as to your take on that thought experiment.
