Buccaneers defensive lineman Albert Haynesworth says he is excited to be back in a true 4-3 defense. "It feels great, it feels unbelievable. Just to get off the ball and wreak havoc, that's awesome," Haynesworth said. "Everybody can say, 'Oh, you're in a 4-3 defense.' But just because you're in a 4-3 defense doesn't mean what I did in Tennessee and I had to learn that the hard way [in New England]." The Patriots released Haynesworth on Tuesday and he was claimed Wednesday by the Buccaneers. Haynesworth, who has 30½ career sacks, emerged as one of the top tackles in the NFL during seven seasons with the Titans. But he's been a huge disappointment since signing a seven-year, $100 million free-agent contract with Washington in 2009.
