The Michigan and Ohio State rivalry is always entertaining, whether it's players or fans going at it. But when the coaches get involved, you know it's serious.

Ohio State wide receivers coach Zach Smith tweeted a picture sent from Michigan's staff to a recruit comparing Smith with Wolverines' wide receivers and passing game coordinator Jedd Fisch. Smith included a caption asking, "U Mad Bro??" in mocking the flyer sent by the rival to the north.

Smith sent out a few more tweets on the flyer, including a prediction of what will take place on the field when the two play each other in November.

Check my Resume... And if it's confusing... Check my live resume next November. It will be the same resume as the last 3 Novembers. 💯 — Zach Smith #Zone6 (@CoachZachSmith) June 7, 2015

The Buckeyes' receivers coach finished the twitter response by showing off the hardware he has won.

Smith also received support from former Buckeyes offensive coordinator/current Houston coach Tom Herman, along with Ohio State linebacker Raekwon McMillan.

Gloves are off. I'd be proud to have @CoachZachSmith coach TD or Maverick. How many Gold Pants does that guy have? https://t.co/5cnV2mLV9H — Tom Herman (@CoachTomHerman) June 7, 2015

They taken shots at @CoachZachSmith , but they don't realize he the illest. — Raekwon McMillan™ (@Kwon_daTRUTH) June 7, 2015

Smith and the Ohio State staff have bragging rights and a lot to back their argument. That doesn't take away from the trash talk, though, and the buildup for this future meeting between the bitter rivals.
