It absolutely happens, regularly in other sports, even big sports - see Italian soccer - NBA. Don’t think for a second that it couldn’t happen. Conferences do this regularly - see Oklahoma this yeah. Officiating needs to be taken over by the ncaa to be made fair but isn’t because conferences like being able to manipulate results.
It can and does happen. One hopes they call it fair... and errors are just that. But we all know enough to call out patterns.
