Mateer just torched Illinois State for 392 yards in his DEBUT, shattering Baker Mayfield's opener record! The Washington State transfer looked absolutely dialed in, connecting on 30 of 37 passes while the defense held the Redbirds to a pathetic 34 passing yards. Keontez Lewis was money too with 119 receiving yards. This offensive rebuild under Arbuckle is already paying dividends - the Sooners outgained them 495-151! What did you think of Mateer's record-breaking performance? #Sports #Football #SoonerNation
