What a completely ridiculous strawman argument.
If Terrence Newman quit working out and went on the 100% Pizza Hut diet and ballooned up to 245 lbs. in the offseason, are you saying the Cowboys shouldn't have a problem with it because he tried really hard in previous years? "There's no loyalty in football"? What the heck does that even mean in this context? The Dolphins are paying Taylor SEVEN POINT FIVE MILLION THIS SEASON, and they're paying him to be the best football player he can possibly be THIS SEASON. And unless he's doing everything he can possibly do to be the best football player he can be in 2008, he's basically stealing money for this year from his employer. Maybe you happen respect thieves, I don't. Frankly, if I were the Dolphins I could give a crap what he did previously. Matt Light isn't going to play any less hard on Jason Taylor in November because he had a really good 2002.
If Tony Romo decided he was just going to focus on golf full time in the offseason, not attend a single Cowboy event, grow a beer gut and just show up at training camp thinking he could just pick up where he left off everyone on this board would be freaking about it ... but because you and some other idiot Cowboys fans have some completely illogical hatred for Bill Parcells, you're supporting a low class move by Taylor. Peyton Manning and Tom Brady are attending all offseason events, I'm going to assume they have them for a reason.
Jason Taylor is under contract to be the best Jason Taylor he can be, and he hasn't attended a single team event in the offseason. Hasn't lifted a single weight. Hasn't been to one single conditioning event. He's reportedly dropped 30 lbs. because of the dancing contest, and considering he like no body fat I'm going to assume that's all muscle mass, which means he'll have less functional strength on the football field. This is going to effect his ability to play the game. Tell me, what NFL organization would be happy with that? This isn't a "Parcells thing". Every single team in the NFL would be unhappy with that, and with good reason. It's bush league. Put half the effort into beating Tom Brady that you're putting into beating Kristi Yamaguchi this offseason ... what's "tyranical" and "unfair" about that when you're paying the guy 7.5 million?
Again, Jason Taylor has every right to persue acting or modeling or professional dancing if he wants to. Just quit football and do it on your own time, and stop stealing money from the Dolphins and cheating your teammates and employers who are depending on you.
