There are essentially 3 “traps” reffing can fall into when it comes to college basketball. There’s not a single sport greater than basketball where the refs have more direct influence, so poor officiating can ruin the experience.
1. Overcharging. When refs decide everything is a charge from lazy defenders, and this has largely been improved over the last decade or so from a series of rule changes, and was a plague for years. Small sample size so far this year, but haven’t seen any egregious examples of this yet. Former “charges” are correctly being called as blocks.
2. The flailer. This is when an offensive player tilts their head back awkwardly the second there is the slightest bit of contact from the defender, and often shouts or flails. This is even coached into everyone these days. It’s such an unnatural and awkward motion, and obvious when it’s not legit. This gets over-called a ton. It can be off-ball too. There was a play last night in the Purdue Tennessee game where the Purdue player set a pick, and the Tennessee player ran into the Purdue player who started moving backwards right before contact and then the Purdue player screamed and flailed his arms up. Whistle. Foul on Tennessee. For what??? Running into an illegally moving player who picked you? Infuriating.
3. Overreffing. Basketball is often a crowded, physical game, that can be ruined by refs with a quick whistle. Sometimes entire team strategies are to “get a player in foul trouble,” which is viable when you are constantly forcing the physical contact yourself, and refs decide they have to get involved. Overreffing at the end of games in general, especially close ones, can be problematic too.
