On Sunday evening, former Ohio State wide receivers coach Zach Smith unleashed a profanity-laden tirade on Twitter (tweets can be found below) aimed at Texas Longhorns head coach Tom Herman and Herman's wife, Michelle. In the rant, Smith accused Tom Herman of cheating on Michelle Herman while threatening to expose other transgressions committed by the Texas coach.

Zach Smith and Tom Herman were co-workers on the Ohio State football staff from 2012-14, when Herman left to take the Houston head coach job. By all accounts the two assistants were close during that time and even took many recruiting trips together. However, signs that the relationship had turned sour came in August when Ohio State opened an investigation into how the athletic department handled domestic violence accusations made against Smith by his ex-wife, Courtney Smith. The investigation ultimately led to a three-game suspension for current Buckeyes head coach Urban Meyer.

Herman found his name in the middle of the controversy, when an Aug. 11 report from Jeff Snook said that Herman was responsible for alerting reporter Brett McMurphy to Zach Smith's previously unreported 2009 arrest, when Zach Smith worked under Meyer at Florida, afterCourtney Smith, alleged he abused her. Snook alleged that Herman had been upset because Zach Smith helped Ohio State land a commitment from 247Sports Composite five-star wide receiver and Austin, Texas, native Garrett Wilson , who picked the Buckeyes over Texas. Herman later denied the report, stating that he and his wife had only assistedCourtney Smith financially in March 2017.

Herman's name would come up again, however, after Ohio State released a 23-page report following the investigation into how Meyer and other staff members handled the domestic violence accusations against Smith. The report stated that an unnamed Buckeyes staffer, along with "one or more high school coaches," had attended a strip club with Zach Smith during a recruiting trip to Florida in May 2014. An Ohio State spokesman later confirmed that the unnamed staffer was Herman.

That was the last we had heard publicly about Tom Herman as it relates to Zach Smith until Sunday, when Zach Smith released a series of tweets about the Longhorns coach. Scroll up to see what Zach Smith had to say. PLEASE BE ADVISED THAT SOME OF THE TWEETS CONTAIN EXPLICIT DETAILS AND LANGUAGE.
