Big 6 sims are faring worse than mid major sims. I suspect it's because they're shooting for - and losing - a higher quality recruit in line with baseline prestige. Totally speculative, but if true, that's probably a simple tweak, if they cared to fix it. Other than that, neglecting to fix hiring at the same time is why we've ended up with half empty big 6 conferences. Currently, those teams have to crash before anyone who is interested is qualified, and at that point, you're usually better off with your current team. Fixing hiring will go a long way toward improving the supply/demand issue.
