Most training camp battles are about new players trying to make the roster. Much of the focus is on UDFAs and late-round picks. Established veterans are secure. For most teams, so are the high-dollar free agents they acquired during the offseason. Things are a bit different with the Dallas Cowboys. They have only signed three outside free agents, and all were on low-cost contracts that make releasing them palatable. We have seen players like that never make it out of training camp with Dallas before, the most recent being Ha Ha Clinton-Dix. This looks like another year that could happen to at least one.
