One of my favorites was ECU at UNC mid 2000's Not sure if it was CJ Wilson or Linval pursuing the UNC QB towards the sideline but they checked up only to be shoved in the back illegally by UNC player and Ref promptly calls Unsportsmanlike Conduct call on ECU for hitting the UNC QB on the sideline when our player got plowed into in the back and shoved into the QB.
I think that game was also one of the only times I saw an offensive player get called for a facemask when the ECU RB stiff armed the UNC defender by the face mask briefly . Literally happens all the time by RB's and WR's but you rarely see it called. I think the famous Ron Cherry was involved.

I will say ECU playing Cincinnati with AAC refs we know the deal and that is they are bad. Heck last week they swallowed a flag on the TD run back when our guy was literally tackled. If we are to beat UC it like Vegas where you need a knockout to win and don't let it go to the judges.
