Not everyone. Just a particularly loud section of State's fan base. We'll see what the serious money guys feel like paying for, and see if there's more structural changes to come. Corrigan may have written that letter firing Doeren but it's not a given that he would have acted without prompting. It's also not a given that more changes are coming, but Corrigan is losing the money generating race to schools with WAY less resources and doesn't seem to even think it's a problem. A lot depends on how engaged the Chancellor feels like getting, but this is not Randy Woodson who wasn't really bothered with athletics so long as they weren't an embarrassment and a drag on other programs. Howell ain't that detached. There was a lot of friction between the Admin and Athletics over the Wade debacle last spring. That hasn't gone away in the meantime and probably has gotten worse.
If they do end up doing the big dumb thing, then Rivers at least fires up the grass roots enough to goose small dollar donations in the short term. But if State goes that way, they're putting a bandaid on a wound that needs stitches. Honestly, if they just let Corrigan hire from the traditional list of candidates without changing the financial structures, they're probably doing a less desperate version of the same thing.
Also, I've heard a few semi-rational people suggesting that Rivers might be a good fit for the GM position, like what Luck is doing at Stanford. Sounds far-fetched but I'm certain they'll at least consult with Rivers since his son is State's highest profile recruit in a hot minute.
