Jones went undrafted out of Southeast Missouri State in 2007. He is 28 years old. Measurements are 6'3" 262lbs. He played with the Ravens from 2007 until 2012. He worked as an OLB, DE, TE and all ST units. He signed with Kansas City in 2012. There he went on to be one of the Chiefs best STer's.
He is basically a special teams ace. I'm sure Dallas will try to get George Selvie type production out of him, but I'm not sure lightning will strike twice. Apparently his specialty is recovering muffed or fumbled punts and kicks. He has recovered quite a few over the years.
