Redskins' No. 1 tailback: Will favorite Rob Kelley hold off rookie Samaje Perine?

Rob Kelley, who came out of nowhere in 2016, is the favorite to open the 2017 season as the Redskins' starting running back. Here are the latest odds from BookMaker.eu.

 

When the Redskins start OTAs on Tuesday, Rob Kelley will line up with the first team.

But the undrafted second-year pro out of Tulane is no lock to start the season as the No. 1 back, according to a major offshore sportsbook.

Here are fresh odds from BookMaker.eu on the Redskins' starter in Week 1:

Rob Kelley -150 (risk $150 to win $100)
Samaje Perine +125 (risk $100 to win $125)
Chris Thompson +1000 (risk $100 to win $1000)
Matt Jones +2500 (risk $100 to win $2500)
Field +500 (risk $100 to win $500)

Kelley won the starting job last November over Matt Jones and acquitted himself well. He finished with 704 rushing yards, a 4.2 yards-per-carry average, and seven total touchdowns.

This offseason, he's earned raves for his commitment in the weight room.

The 5-11, 233-pound Perine, Oklahoma's all-time leading rusher, has greater upside. How quickly he absorbs the playbook will be critical.

Chris Thompson should remain the primary pass-catching back, while Jones might not even make the roster.

"I think Kelley will win the opening day job because he is already a proven NFL back," said SportsLine expert Josh Nagel, who followed Perine's college career closely.

"But Perine could be a steal as a fourth-rounder. He's a bruising, physical back. Set the NCAA single-game rushing record against Kansas. The concerns are that he already has an injury history and might lack NFL explosiveness.

"I've seen some comparisons to Ron Dayne -- a huge back who dominated college but couldn't get traction as a pro. But I think Perine is more explosive than most observers realize."

Look for Perine to impress in training camp and get significant carries early, especially in short yardage and near the goal line.

But back Kelly at -150 to be the Week 1 starter.
