One of the more fascinating storylines in New England Patriots training camp, thus far, has been in the running back room. Between the veteran Rhamondre Stevenson and rookie TreVeyon Henderson, the Patriots have a fun one-two punch and position battle going on.
Elsewhere in the AFC East, though, there is another significant running back storyline that isn't so positive. While the Patriots have some healthy competition going on, the Buffalo Bills suddenly don't even have their star running back on the field for camp in James Cook.
When it came time for practice in the Bills' most recent practice, Cook showed up to training camp, Sunday, in his street clothes and did not participate.
