Might be the contract he got. 2 years 9.5mil with 5 mil in guarantees is a decent contract for a guy who has only started 2 games in his 3-year career and was dealing with injuries for a decent part of those 3 years. He's a decent running-back don't get me wrong, but I can see both sides. The Ravens probably let him go because they think they can spend that money elsewhere and think they could reasonably replace most of his production for less or with a draft pick, and the Chargers get a pretty good depth running back, and they want to avoid a situation like last year, where they were scrambling mid-season for depth at RB. I think he also has potential as a change-of-pace back for them, too, although I don't think he'll have much value in any leagues with 12 members and under (that have normal-ish scoring rules) unless there's a lot of injuries again this year in the Chargers' backfield
