Everybody likes a good explanation on penalty calls. General terms like holding, clipping or pass interference are so boring.

Fortunately, veteran Big Ten referee Dave Witvoet came through for us. Early in the second quarter of the Iowa-Maryland game, Hawkeyes tight end Jake Duzey fumbled following a reception, and Maryland recovered at its 32-yard line. But Terrapins defensive back Anthony Nixon was flagged for unsportsmanlike conduct.

Specifically, "removing his helmet ... in disgust," Witvoet said.

Somewhere, Ed Hochuli is smiling.
