"The Cowboys claimed defensive tackle Thaddeus Gibson off waivers after he was released by the Tennessee Titans. To make room for Gibson, the Cowboys released tackle James Nelson." He was a 4th rounder drafted by Pitt in 2010, he then was with the Niners and in 2011 Chicago. Last year he was on the Titans PS, they waived him and the Boys claimed him. I would assume our DL coach has something to do with this move.
