Best case scenario, it's very possible for NU to go 6-3 the rest of the way to finish 7-5. Now, some people would say that "Riley finished strong, so the team was on the uptick." It's very similar to the first year going 6-7, so that going 9-4 seemed like such a great improvement. Is 7-5 a good year? I say no, and I would have seen enough from Riley and his staff to say "this experiment isn't working", time to go to a new plan. And that 7-5 season seems like best-case scenario right now.
Mike'l Severe tweeted out that 30% of the coaches hired in 2010-2012 were fired within 3 years. People act like NU is the only school without much patience for their football coach. It's happening all over the place. It's not unique to Nebraska.
