The writer is assuming Wilfork would have been a top target for Miami. He's old, broken, and expensive, I don't see that as an appealing combo for a team looking to get younger and better. Wilfork is a nice option for a team who is a DT away from a great front 7, not a team who defensive strength is already the front 7. Between signing Wilfork or Mitchell, the Dolphins made the right choice regardless when Wilfork was available. And no one should think this was some coup by Belichick on the league. Wilfork's agent knew all about what was going to happen, but what could they do? Let Bill screw them, which is closer to reality. It's not that teams didn't get to rush to sign Wilfork as much as he couldn't go sell himself to anyone.
More and more I read articles or hear commentary from sports "journalists" like Hyde and Colin Cowherd who begin their story with a sketchy premise, then build the rest as if it's a solid accepted fact. They are not writers, journalists, or newsmen. It's a new age of mudslinging when it doesn't matter what you write if you can get hits to your page.
