RB DeMarco Murray will not be counted on to carry the full load for the Eagles like he did in Dallas, where he accounted for 77 percent of the team's total carries, outpacing the second-leading rusher, Randle, by 341 carries. The presence of Ryan Mathews, himself a two-time 1,000-yard rusher, and Darren Sproles should mitigate the workload placed on Murray.
Last year, among the three top running backs, the split on carries went 75 percent to McCoy, 14 percent to Sproles and 11 percent to Polk. It's hard not to envision HC Chip Kelly opting to creep those percentages closer to something like 55-60 percent for Murray, 25-30 percent for Mathews and the remaining touches for Sproles.
Conveniently enough, we project Murray for 58.1% of the touches, with Mathews checking in at 27.1% and Sproles getting the remaining 14.8%. The article also notes that among the seven running backs who carried the ball at least 380 times in a season (and also played the following year), only two played more than 12 games, and the overall YPC dropped from 4.60 YPC in the 380-plus carry seasons to 3.60 YPC the following year. Four of the seven running backs played fewer than nine games. It remains to be seen if Kelly's superior sports science program can help Murray buck this trend.
