Penn State cornerback A.J. Harris has allowed just one touchdown in coverage this season, holding opponents to 25 catches on 43 targets his way. The transfer from Georgia fit in well with the Nittany Lions' aggressive defense, which ranks seventh-best in fewest points surrendered per game (15.8). Harris has 45 total tackles to go along with an interception and three additional pass breakups.

Runner-up: Nolan Rucci, OT

(7) Notre Dame: Riley Leonard, QB

There is an obvious MVP for Notre Dame this season -- transfer quarterback Riley Leonard. The former Duke standout has remained healthy this season while accounting for 33 total touchdowns (18 passing, 15 rushing). Leonard ranks seventh among all FBS quarterbacks with 831 yards rushing this season and his addition has the Fighting Irish on the cusp of its first championship game appearance since the 2011 season. 

Runner-up: Jordan Clark, CB

(8) Ohio State: Caleb Downs, S

There is a reason why Caleb Downs ranked as the No. 1 transfer prospect last cycle. The former Alabama five-star freshman arrived at Ohio State last January as a major portal pickup that projected to add another elite piece to the Buckeyes already loaded defense. Downs has 71 total tackles, an interception and a punt return for a touchdown so far in his contributions to Ohio State this season. Downs earned CBS Sports First-Team All-America honors. 

Runner-up: Will Howard, QB
