Listed measurements: 6-foot-1, 207 pounds.
2021-22 year, eligibility: An early enrollee this past spring, Buchner has four seasons of eligibility ahead of him.
Depth Chart: Irish head coach Brian Kelly may claim a position competition is active at quarterback this preseason, but Wisconsin transfer Jack Coan will start for Notre Dame on Labor Day Eve (40 days), and sophomore Drew Pyne will back him up. Beyond them, though, Buchner will be competing with junior Brendon Clark and his balky knee for third-string reps, valuable opportunities for any young quarterback.
