New Mexico State football head coach Jerry Kill made good on a promise to his players Sunday -- getting a tattoo after they helped him win a bowl game ... and it's MASSIVE.
Coach Kill made the agreement with his squad back in December ... telling his team if it defeated Bowling Green in the Quick Lane Bowl in Detroit, Mi, he would get the ink on his arm.
And, after his players got the 24-19 dub -- he kept his word ... hitting a tattoo shop in Las Cruces, N.
