The Eagles were extremely close to making the Super Bowl last year, and to the extent they got worse in the off-season, nearly $40 million can make up all of that ground and then much more.
The number that's compelling to me is the Arizona Cardinals' number. They have to do something, and other than trading Boldin I just don't see what their options are. And the Eagles have plenty to sign him to an extension, plus he fills a need that will make them great. I don't see how Arizona can come out of the post-draft period with that little money. One of those interesting little side stories to watch -- but I bet the Cards will ultimately send him to Philly, and, in the process, make another NFC team a major force to be reckoned with. Such is the cap.
