So if the Bills used the transition tag on Byrd, he and his agent would shop around for the best deal. Let's say Cleveland comes along and offers $9.5 million per year, then Chicago comes along and offers $10 million per year. Then Philly chimes in and offers him a gaudy $10.5 million per year. The Bills look at that and say, "holy crap, we can't afford that," and then Byrd goes to Philly and the Bills get nothing.
How does that help the Bills? Why would they do that?
