One of the few guys on offense who can expand his role in 2014 is Eagles RB Chris Polk, and given the success he had last year, I’d expect Polk to produce even more as LeSean McCoy’s backup than Bryce Brown did last year.
Part of the reason the Eagles were willing to part ways with Brown was the emergence of Polk, who made the most of his very limited opportunities on offense last year. Polk only got the ball 11 times, but he rushed for three touchdowns and 98 yards, averaging just under nine yards per carry. He scored a touchdown against Denver in Week 4 on his first carry as a pro, a 4-yarder.
Polk also plays special teams which is another reason the Birds could part ways with Brown. Mosher feels the team would give a lot of work to Polk if McCoy were ever to miss time, even though the team is going out of its way to say newly-acquired RB Darren Sproles isn't a receiver. Polk is someone to keep in mind as a handcuff to McCoy and we should get a better feel as to what his role will be this season during camp.
