You do realize we aren’t talking about the refs missing some holding calls? The referees quite literally never call holding against Nebraska’s big ten opponents. Not, “some”, or “a few”, literally not a single holding call, for years!!!
2018 Nebraska vs Minnesota was the first time since 2016, that holding was called on a Nebraska opponent in Big Ten play. That has continued and a holding call has not been called against an opponent since then, but you act like the referees just happen to be missing it, the same referees that openly celebrate Wisconsin touchdowns against Nebraska on national television???? Sure, no bias at all...
