As Eagles center Jason Kelce told ESPN two months ago before the Birds’ great run:

“Last year, it just seemed like everybody was clicking. We had guys like Brent Celek who had been here a long time who was very accountable, Torrey Smith who had been in the league for a long time, very accountable. Mack Hollins was a guy that gave great effort. LeGarrette Blount and all of these running backs that, they had their limited amount of stuff that they had to know, but they knew what to do, and they knew how to do those things. That’s what we’re missing. We’re missing that accountability.”
