Sophomore Nick Bosa, redshirt freshman Jonathon Cooper, freshman Chase Young and incoming freshman Alex Williams are the only other defensive ends on the roster.The Buckeyes signed 21 prospects during Early Signing Day. Another Ohio State target — four-star defensive end Jayson Oweh — will commit to either Ohio State or Penn State later during the second half of the All-American game on Thursday.
