The Tom Herman era of Texas football  is starting on a low note.  The 23rd-ranked Longhorns were upset 51-41,  by the Maryland Terrapins in Austin on Saturday.  Terps quarterback  Tyrrell Pigrome threw for two touchdowns and ran for another as they  built a 30-14 halftime lead.  The Longhorns came within three points in  the second half, but Maryland closed the door and pulled off the  season-opening road win.  Shane Buechele threw for 375 yards and  accounted for three touchdowns for Texas.
