Here are The Post’s college football rankings following Week 1:

New starting quarterback Julian Sayin looked the part and the Matt Patricia-led defense, with just three returning starters, was terrific in an impressive win over preseason No. 1 Texas.

The rebuilt Tigers defense looked fantastic, keying one of the best wins of the Brian Kelly era, at Clemson. The unit held Heisman Trophy candidate Cade Klubnik and Co. to 230 yards of offense and shut them out after halftime.

We didn’t learn anything about Penn State in its 46-11 shellacking of Nevada, and we won’t be able to glean much in its next two games, against Florida International and Villanova, either.
