It really doesn't matter. I get that the PAC and Big 10 don't want to have an Ole Miss in their league, and like to have their leagues be top academic schools, but the two really have nothing to do with each other.
I know CW keeps bringing this up about Nebraska being in the Big 10 gives them research dollars, or UCLA going to the Big 10 was going to help Iowa get research dollars, but I can assure everyone, there is ZERO impact of what athletic conference you are in to research. Not that there isn't much, very little, or a tiny amount, but zero. I'm sure he's looking at that Big 10 alliance page where they say something $X in research. That's simply a sum of research dollars the individual universities got. That Alliance basically gets a discount on journal library access and software licenses through economies of scale.
As someone that's been in research including with schools from all major sports conferences, and as someone who reviews proposals, athletic conference membership has absolutely, and completely no impact on research. None. The Big 10 research alliance has absolutely and no impact on research dollars. None.
Zero research dollars are granted to an athletic conference. Hell, outside of MIT and probably the ivies and maybe Stanford, Very few research dollars even flow to the Universities.
Research is almost exclusively developed by faculty. They work together with colleagues that fit what they are doing. There is no thought to athletic conference. They might not even know what an athletic conference is. Nor do the people reviewing and awarding these.
