I don't think it's betting services. They release odds that are as close as they can. Then they adjust them if to much money comes in on one side.There's no doubt in my mind that the replay is being used as a tool by conferences or worse betting services to affect the outcome of games. It's been pretty obvious for a couple of years in the NFL, now it's in college football. On the field calls are being overturned with almost no evidence, clearly, the replay officials are either following someone's agenda or have usurped completely the officials' role on the field. I don't believe this was the intention of replay.
As for conferences, idk. I'm sure like any business there is politics to it.
I'm struggling though to figure out why anyone would be so dumb and blatant if they are doing something shady. Seems like a good way to get exposed.
