Ronnie Brown traded to Lions

The Eagles have traded RB Ronnie Brown to the Lions in exchange for RB Jerome Harrison and a 7th-round pick in 2013.  With RB Jahvid Best once again dealing with a concussion, Detroit was looking to add to its backfield.  Brown immediately becomes the best bet for carries while Best is out.  Don't expect big-time production though.  Brown is almost 30 years old and averaged just 2.9 yards per carry in 6 games with the Eagles.  The move also makes us wonder if the Lions are expecting to be without Best for a large chunk of time.  Harrison, meanwhile, heads back to Philadelphia, where he spent 12 games last year.  He averaged just a shade under 7 touches per game in those contests, and is looking at a similar workload the rest of this season behind LeSean McCoy.  Harrison won't be a fantasy option without an injury to Shady.
