It would be easy, perhaps, to build a narrative around Chip Kelly's "positive reinforcement" in contrast to Malcolm Jenkins' "holding players accountable," and come to the conclusion that one or the other had more to do with the Eagles' upset win against the Patriots.
Kelly showed each of his players film of one standout play they made this season on the eve of Sunday's game in Foxborough, Mass. Several said it was the first time he'd done so, but the principle behind the exercise wasn't any different than Kelly's core belief about accentuating the positive.
"I think positive reinforcement is a positive way to be successful," Kelly said Monday.
