Former Ohio State assistant football coach Zach Smith told USA TODAY Sports he was “done trying to keep quiet” after a tweet storm Sunday night where he alleged University of Texas head coach Tom Herman cheated on his wife “several times.”

John Bianco, a spokesperson for Texas’ athletic department, told USA TODAY Sports the school would have no comment on Smith’s allegations.  

Smith posted a screen grab of what appears to be a text exchange with Herman as Smith’s tweets began to roll. “I’m going to share EVERYTHING about you,” Smith wrote. 

The response purportedly from Herman: “OK cool. Hook Em.” 

“I’m done trying to keep quiet,” Smith told USA TODAY Sports in a phone interview. “It’s about being honest. I’m done with coaching and I know everything about Tom Herman. Everything. He’s the biggest (expletive) I know.”

Smith has lashed out before against Herman, who coached alongside Smith under Urban Meyer at Ohio State; however, the allegations against Herman about his wife, Michelle, were the most forceful.

While he mentioned on Twitter he had info on other coaches, Smith said he had “nothing against” any other coach besides Herman. 

Smith wrote that the “problem (with coaching) is that “(you’re) not ‘supposed’ to be real.” He alleged Herman drank to excess, often with Gatorade G2 and vodka along with various claims of extramarital affairs. The most recent alleged affair took place about three years ago, Smith said in a text message to USA TODAY Sports. 

Smith’s ex-wife came forward last summer with allegations Smith abused her. The fallout resulted in the firing of Smith and an investigation that led to a three-game suspension of Meyer. 

Meyer and athletic director Gene Smith – who also was suspended – were aware Courtney Smith called police to her home in October 2015. Zach Smith was not arrested in the incident. 

Courtney Smith was granted a three-year protection order last month. Her application that became public included a trespassing summons issued to Smith for an alleged violation earlier this year. 

Zach Smith has repeatedly denied abusing Courtney Smith.
