Casey Printers was never that good.
Running backs are easily replaced by cheaper young talent, although I'm a bit surprised about Cobourne.
5 years ago, during the Katz era, Hamilton was very good at bringing in big name weapon players (Keith, Holmes, Brazzell, etc) they had like 3 star RBs and 7 star receivers on the roster, couldn't possibly put them all on the field at the same time, and completely neglected the line of scrimmage and secondary. The worst possible way to build a football team.
But now they are solid all around with tons of young talent. O'Bie knows what he's doing.
As for Baggs, maybe I'm reading to deep between the lines but it smells like he rubbed Cortez the wrong way. If it was a salary move it would have been done between December and February, or just before camp.
