If Haynesworth simply doesn't want to play in a 3-4, then we should stay away form him. At this point, you have to wonder what the hell his problem is. I wasn't opposed to trading for Haynesworth until now, as I thought he'd be a decent enough teammate to show up for mandatory workouts. Looks like I was wrong in a big way.
Let's stay away from this guy while we still have momentum building in the locker room. The Mankins issue is volatile enough as it is without adding Haynesworth into it.
Never heard of a guy who threw such a fit over a position change after getting paid a $21 million bonus. Either there's more to the situation or Haynesworth is the biggest baby in the NFL.
Also, the Pats have never played a "Base 4-3" defense. I'm not sure where people got that idea, but Belichick has always run a Base 3-4. Just because we're using a certain package more often in a given season doesn't mean it's the new base defense, especially since the Pats reverted almost entirely to the 3-4 during the last half of 2009.
That said, I think Ty Warren could be a very effective 4-3 tackle. He essentially does the same job at 3-4 DE, controlling gaps and stopping the run.
