ACC refs are horrible.
Flake and Diaz need to be more critical of the refs.
Back in 2016, Dabo was furious when he felt a certain ACC ref(that lives in Columbia,SC) unfairly penalized Clemson in a conference game, so they told the ACC office to not assign him to anymore of their games, he was biased against Clemson.
He did call the Clemson vs. Pittsburgh game later that season, and called multiple questionable 1-2 really bad PI calls, and Clemson lost to Pittsburgh at home.
I have no doubt these ACC officials who live in South Carolina, North Carolina, Virginia, are biased against Miami. I see evidence of it every week.
