There are some good points here. However one thing is lost in this entire post. How extremely bad this team has looked for 2 1/2 years. The wins have been moderate to ugly and the loses have been even uglier. Its the entirety of the work that makes the rational person question whether Riley could ever get us to where we want and even more importantly consistently stay there. Keeping a coaching staff that is failing this bad because of what a potential coaching candidate might be saying, or what the AD is expressing publically and for what the present coach is saying is really bad business. You need to look at the body of works and not just "coach talk". Just my opinion.
I agree with you that the entire body of work needs to be analyzed. But you also have to analyze the situation he inherited (no I don't really believe it was as bad as everyone makes it out to be but I also don't think it was great either) as well as the fact he was bringing in a completely new system that hasn't been implemented until this year (again right or wrong is up for debate). I also don't have a problem with questioning whether or not he is the right or wrong coach, I question it as well.
However, me saying what if it gets better is the same as you or anyone else saying what if Frost comes here and wins. Both are unknowns and both are unknown probabilities. I am almost completely certain, though, that if SF comes here and struggles for 2.5 years similar to Riley, there will be much less pushing for a change. And that's where I have the problem. The double standard makes no sense to me.
The other problem I have is that it only seems to be ok to say what if, if it involves removing Riley. No one seems to be allowed to say what if the team gets better. What if next year is better. People want to look at the past 2.5 years as your evidence, but the past 2.5 years wasn't his players or system. People also want to look at the past 1.5 years of SF, but that isn't his players, and there never needed to be a system change when he arrived. What if SF can't maintain that level (similar to Bo)? The comparison is apples to oranges.
Most coaches today say they need a minimum amount of time to get their style, culture, whatever other coach speak into place. Some can do it quicker, some take more time, but what that minimum amount is should be the same. I personally draw that line at 4 years. Like I said with PSU, they were completely stagnant to regressing under Franklin, until it literally just seemed to click. Their o line was garbage, and now it is good. Their qb play wasn't great, now he is heisman material. Just as you can draw comparisons of situations where things didn't get turned around with more time, there are situations where it did.
Regardless, though, I like the discussion and getting other viewpoints and I'm glad I'm not the ad making the decision. No matter who is coaching NU next year, I will support them and hope we go undefeated and win a NC, which I'm guessing (hoping) everyone else on this board will be doing as well.
