Tom Herman's wife trolls Zach Smith with T-shirt

Michelle Herman, the wife of Texas head coach Tom Herman, fired back at former Ohio State assistant coach Zach Smith on Saturday, a week after he accused her husband of cheating on her in a series of tweets.

Prior to the Longhorns' game against Iowa State, Michelle showed off a T-shirt emblazoned with: "OK, Cool. Hook 'em." The phrase is a reference to Tom's alleged response to a text message from Smith.

Proceeds from the sales of the shirt will benefit Women Called Moses, an advocacy group that helps victims of domestic violence.

Michelle was also spotted wearing the shirt at Saturday's game:

Smith was fired by Ohio State in July after his past domestic violence allegations were reported by college football insider Brett McMurphy.
