All season long, it was a foregone conclusion that New York Giants running back Saquon Barkley was a cinch for the NFL Offensive Rookie of the Year award.

Now, after consecutive weeks in which he failed to gain 100 yards from scrimmage, Barkley has come back down to earth. Many still believe, however, that he’s done enough to earn the honor.

Barkley’s main competition could come from the player taken directly in front of him in the NFL Draft, Cleveland Browns quarterback Baker Mayfield.

Mayfield has been surprisingly good as a rookie, logging in a 6-6 record as a starter this year for a team that had won just one game over the past two seasons.

In Week 16, the former Heisman Trophy winner completed 27 of 37 pass attempts (73.0 percent) for 284 yards with three touchdowns and zero interceptions for a 121.9 passer rating in the Browns’ 26-18 win against Cincinnati.

He has 24 touchdown passes this season in 13 games, surpassing Andrew Luck (23 touchdown passes in 2012) for the second-most touchdown passes by a rookie quarterback selected No. 1 overall in the common draft era. Only the great Peyton Manning (26 in 1998) had more passing touchdowns as a rookie quarterback selected No. 1 overall in the common draft era.

Mayfield is also wavering 257 yards passing per game (which averages out to 4,112 yards over 16 games) and has just 11 interceptions on the year. He’s been quite poised for a rookie and has even thrived in the face of his head coach being fired in-season.

But Barkley has done his damage as well. He needs 114 yards in the Giants’ final game this week against the Dallas Cowboys to become the third rookie in NFL history with 2,000 yards from scrimmage. Eric Dickerson (1983) and Edgerrin James (1999) are the others.

Barkley also has a team-high 87 receptions on the season. He needs two receptions against Dallas to set an NFL record for catches by a rookie running back. Reggie Bush holds the mark with 88 receptions for New Orleans in 2006.

The sensation from Penn State scored on a one-yard touchdown run on the Giants’ first possession against the Colts in Week 16. It was his 10th on the ground this season. That tied the Giants’ record for a rookie running back; Bill Paschal ran for 10 touchdowns in 1943.

The odds are that Barkley wins the OROY award going away. Bovada has him at -500 to win the award over Mayfield, who is listed at +330.

That doesn’t mean it won’t be close, especially if Saquon has another off week and Mayfield has a strong showing against the Ravens in Baltimore this Sunday.
