But basketball officials are so lacking in imperfection cheating is beyond them. Schools cheat in admissions, and not just in athletics. Coaches cheat in recruiting. Players take money from agents. But the officials, they are immune from dishonest motives.
As for real visible proof, lets start with my football example from above. There is no good faith mistake defense for those officials. What did the Big Ten do to discipline them?
Here's a pattern on which to keep an eye. It varies to a certain extent, but Michigan, Sparty, Indiana, the Turtles, Brutus and Bucky are the league's important basketball franchises. The other 8 teams exist to provide them with competition. So, watch for officials swallowing their whistles when one of the big 6 are playing poorly. It keeps them in the game where they would be otherwise far behind. MSU is particularly shady because their fouling is so obvious. Once the Big Six team recovers its equilibrium the officiating starts to even out, the high profile wins and everyone but the untermenchen are happy. That is an observable pattern.
Another similar vein of dishonesty happens, and once again not every official every game but some officials in games that are critical in the league's regular season standings is the guys that will rescue the important "franchise" with a barrage of calls and no calls in a short time, creating a dispositive swing of momentum. This is what obviously happened in the Rutgers Ohio State game. The officiating changed abruptly and became very one sided and quite outrageously so.
But there are other less overtly corrupt things. Like the the officials that just do not like a coach or a program. Again, it is not realistic to believe such biases do not exist. I find it impossible to believe that there are not at least a few officials that think Fran is a prick and some do their best to frustrate him. I'm shit with names so I cannot remember which Eades but of one those two hate Iowa. He inflicts an obvious double standard on Iowa, every game regardless of opponent. I'll bet Rob Dibler knows about the animosity when he assigns that Eades to Iowa games. Other officials may have other enemies, which can be indulged as long as the Big Six aren't getting burned.
Finally, I could give many examples from the past but I'll start noting the calls at the time and we can look at contemporary events simultaneously.
