Cowboys RB Tony Pollard had 13 yards on the ground on those four carries, which certainly isn't ideal but even more so when you take in the fact his longest run was nine yards.
Fantasy Impact
Pollard is very much still the RB to own in fantasy as Ezekiel Elliott's backup, but now heading into his third season, Pollard has yet to show the ability to run in between the tackles effectively. It'll be interesting if Pollard will get more receiving looks as the preseason progresses.
