i struggle with this one... i get the value for new coaches, but i kind of would hate to see it from a selfish point of view - its a big undertaking - i'd rather see movement somewhere else. first off, how do you move someone who loves their current conference? i think it could be balanced by only moving teams around coaching changes, and perhaps by allowing the current HC to make the choice (to go to the correct conference), but even that is far more complex than it sounds, with schedules being set in advance and all.
second, the game is hard-wired for 12 teams to a conference. perhaps a bad decision, but it is what it is now. unwinding that is non trivial - they only support 1 schedule format - they would have to support very many, especially if trying to future-proof the the thing.
finally - stats become messy. conference player of the year, do you just leave that? move it as the school moves? the problem is, regardless of what our preference is, this is unlikely to be trivial from the game developer's standpoints. it just creates so many edge cases to deal with.
i suspect the reality is - the game developers could find a way to make this big instead of huge - but they'd have to make choices based on what was easiest, and people would end up having numerous complaints about the way it was handled. so its probably a head ache either way.
that said... it does feel... kinda hankey, i guess, from a new person's standpoint. so i get the desire to fix it. it just basically sucks, one of those situations where every outcome is a negative - its just, what is the least worst option?
