Looking every bit like the reigning NFL MVP, Lamar Jackson threw for 275 yards and three touchdowns to help the Baltimore Ravens beat the Browns 38-6 Sunday, ruining Kevin Stefanski’s debut as Cleveland’s head coach in a game played without fans in attendance.  Jackson completed 20 of 25 passes and racked up a team-high 45 yards on the ground.  Browns quarterback Baker Mayfield threw an interception on the opening series, the first of three Browns turnovers. Those miscues, two missed kicks by Austin Seibert and an unsuccessful fake punt call by Stefanski contributed to the rout.  Mayfield went 21 for 39 for 189 yards and was sacked twice.  It’s a quick turnaround for Cleveland, which hosts the Bengals on Thursday night.
