Justin Fields threw four touchdown passes and ran for a score in his first game for Ohio State and the fifth-ranked Buckeyes rolled over FAU 45-21 on Saturday in the season opener.  Fields, the five-star transfer from Georgia, made it look easy early, engineering touchdowns on Ohio State’s first four drives. Despite some occasional rookie mistakes that caused the Buckeyes’ offense to sputter in the second and third quarters, Fields finished 18 for 25 for 234 yards and a 51-yard touchdown run.  Tight end Jeremy Ruckert caught two touchdown passes, and Binjimen Victorand Chris Olave also had scoring grabs
