Notorious Michigan backer and sports show host Rich Eisen took exception to Ohio State receiver Jeremiah Smith's guarantee to beat the Wolverines.

CBS Sports spoke to a source with knowledge of the agreement Wednesday, who acknowledged Smith would still wear Nike with the Buckeyes this season. Ohio State signed a then record-setting 15-year agreement with the Swoosh in 2016 to be the Buckeyes' official apparel sponsor.

The Ohio State Buckeyes may be Nike through and through but one of their biggest stars just inked an NIL deal with the swoosh's biggest rival. On Wednesday, All-American wideout Jeremiah Smith reportedly signed on with adidas Football as the latest athlete to join the three stripes.
