The Eagles signed running back Matt Jones to a contract on Wednesday, adding him to a very talented offensive backfield and, long story short, taking a flier on a player who has had a startling fall from grace in his career. Will a new home and a new offense breathe life into Jones’ career, which has been in a downward direction since 2016? The point of this story is not to speculate on Jones’ chances with the Eagles; his performance in the weeks and months to come will dictate that. Instead, the focus is on Jones and what has happened to what once was a very promising career.
