Chris Polk (PHI – RB) With stud lead back LeSean McCoy turning 26 years old and handling more than 300 touches per season (306.5) over the last four years, expect Chip Kelly to ease off the throttle just a bit in 2014. The natural inclination is to expect more involvement for Bryce Brown, but what if Brown is not McCoy’s direct backup in training camp? For the second offseason in a row there are whispers that Brown’s tendency to bounce runs to the outside makes him a poor fit for Kelly’s scheme. The 24 year old Polk, however, embraced his limited role by gaining 54 yards on seven between the tackles runs, averaging 7.7 per carry and adding 40 yards after initial contact.

To properly sell outside zone runs, on one of which Polk scored a 38 yard touchdown, keeping the defense honest with their inside counterpart is crucial. The fact that Brown’s tendencies telegraph where he is headed goes a long way toward explaining his disappointing season. In an extremely small sample, Polk excelled. His insane 1.22 fantasy points per opportunity (PPO) will obviously regress with more touches, as will his 8.9 yards per carry average. A 7.18 yards after contact per attempt (Yco/Att) figure, which was the best of any back with at least 15 combined runs and receptions, fueled an otherworldly 191.5 elusive rating. Over a significant number of touches all of these averages will fall, including his third place (no minimum attempts) 67.3 Breakaway Percent figure. Yet they hint at the potential for more production than the unheralded Polk has been credited with possessing, or than has been priced into his current market value.
