What does Felix Jones do for the Eagles?

The Eagles signed former Dallas Cowboy Running Back Felix Jones last week to a one year contract and will backup McCoy along with young promising backs in Bryce Brown and Chris Polk. The explosive back fits Chip Kelly's system perfectly but with Bryce Brown who was a surprise breakout rookie last year....what exactly can we use Jones for? Well for one Chip Kelly is going to rotate players around maybe even move McCoy to WR and Jones at RB I can easily see at times so the versatility is for sure there but the thing I like most about Jones other than providing a veteran prescience for 3 young running backs is his explosive kick returning. Bryce Brown does have some fumbling issues he must attend to which could be a reason why the Eagles went out and got Jones but as I said, His Kick Returning is spectacular compared to what we had last year which was just plain out unproductive. Rookie Corner as of last year out of Georgia Brandon Boykin took kick return starter and rookie out of Tulane WR Damaris Johnson took punt returning duties. This 2 rookie set didn't work too well and since Desean Jackson is returning to punt returning they could use a explosive kick returner to help and go along with Boykin. Felix Jones only has one career return TD but was not put at the spot a lot not really giving him the opportunity to do it. Watching the small samples we got I can totally see this guy having a pro bowl special teams year. The Eagles will be running many different offensive looks this year including 3 TE sets, 4 WRS, Heck maybe even 3 running backs which would actually be pretty dangerous. Move Brown to FB for the play have McCoy at RB and Jones next to him phew this could be a fun thing to watch as Kelly plays with his toys. It's not the biggest pick up but Jones is another piece to this mysterious puzzle and I personally am intrigued to see what Kelly wants from Jones who by the way when Demarco Murray was hurt last year, he was very productive finishing the year off with around 700 yards from scrimmage and 5 touchdowns. For a backup that's pretty good.
