He almost lost me at trading Champ Bailey. He had a down season which only makes it easier to negotiate a new contract to turn some of his salary into prorated bonuses. CBs play well well into their mid 30s. No reason to get rid of him, he'll be the beneficiary of a defense that forces some early throws... assuming Spags is the choice.
No on Pioli as well. Look at their drafts recently and they have been struggling as well. Mayo was a good pick this year, but Chad Jackson, Merriweather, Maroney, and numerous others in recent years have failed to meet expectations. The Patriots have had some success bringing in FAs but they also spend pretty big as well. Adalius Thomas was paid big bucks and Randy Moss' future is looking bright.
