Chip Kelly is reportedly in a dispute with management in Philadelphia. Kelly and GM Howie Roseman's relationship took a big blow on New Year's Eve when Roseman fired player personnel executive Tom Gamble. Similar circumstances saw Doug Marrone opt out of his contract in Buffalo, and Jim Harbaugh leave San Francisco for more control in Ann Arbor this week. The 49ers are already rumored to be a possible destination for Kelly, should his time in Philly end.
