Amidst all the embarrassment and frustration that Dolphins fans felt in 2007, no individual was a bigger letdown than Joey Porter. He came to town with a mean snarl and a Super Bowl ring that he won with the Steelers. It cost the Dolphins $32 million to snag the loud-talking linebacker after Pittsburgh cut him, but it sounded great in theory: bring in a dominant outside force to line up opposite Defensive Player of the Year Jason Taylor. Well, lots of things are good in theory and end with good people getting ripped off; see Reaganomics. Porter was like that, and the Dolphins defense ended up abhorrent despite the work of Taylor. And Porter was involved in a few off-the-field controversies: he jumped a Bengals lineman at a blackjack table in Las Vegas, he passed out offensive slurs like Christmas cards, and his pit bulls got loose and killed a horse. Still, Miami fans could have lived with all that if he'd just helped the team win.
