I think you mean 2006, which was indeed a great year. But, he has not been even remotely in the realm of a dominant corner throughout his career. If you're using YPA as a featured measure of his prowess as a Shutdown Corner, you'll also find that he was not all that much of a shutdown guy in years surrounding 2006. According to KC Joyner, Bailey ranked 66th in 2004, 36th in 2005, and 56th in 2007.
Anyone who's followed your posts over the last several years understands that you, as a Bronco fan, really want people to believe Champ is a stud. We get it. He had really nice '05 and '06 campaigns. Otherwise, there are/were plenty other corners much better.
