The Oklahoma Sooners as a whole didn't wow anyone in their 2025 season opener on Saturday night, but new quarterback John Mateer certainly did in his OU debut.
Mateer finished the 35-3 win over Illinois State with 392 passing yards, which broke Baker Mayfield's record of 388 passing yards in an OU debut.

It took Sooner Nation just one half to realize they had something special with the transfer from Washington State. Mateer found his rhythm after two disappointing opening drives before leading the Sooners to the end zone in their final three possessions of the first half.
