No team was more active this offseason than the Eagles. Once he became armed with the power to reshape the roster fully in his image, Chip Kelly went to work with abandon, replacing most of his skill players and jettisoning some who didn’t fully “buy in” to the culture. Like him or not, Kelly is a refreshing change agent in a profession that sorely needed one. In his world, there is no time to dawdle. He talks fast, walks fast, coaches fast and now, having been in the role for less than six months, general-manages fast.
