Football is finally back in the air in Columbus as Ohio State returned to the field on Thursday for its first day of fall camp. But the first day of camp revealed something significant for the defense that head coach Ryan Day and defensive coordinator Matt Patricia may have to address with a major decision. Kelly is new to Ohio State this season; he transferred in from Georgia in the winter. Ohio State must've liked what it saw from Kelly during spring practices to start him with the first-team defense on the first day of fall camp. However, if Kelly secures the job simply because Mathews had a subpar camp, Ohio State may face challenges in the secondary this season.
