Thomas Jones rushed for over 200 yards last Sunday at the age of 31 and he believes he can continue for another four or five seasons. "I can play another four or five years if I want to, God willing, if I stay healthy," Jones said Friday before the Jets left for their next game at Oakland. "It's like, 'Are you kidding me?'" coach Rex Ryan said. "It almost looks like he's upside down. The size of those arms, they should be on the legs." Most NFL running backs begin to breakdown physically by the age of 30. "I don't even know who came up with that rule," Jones said defiantly. "Whoever came up with that rule obviously didn't play running back in this league, didn't prepare like I prepare, didn't watch film like I watch film, didn't take care of their body like I take care of my body. "Physically, I feel like a rookie. I don't feel like I've been in the league for 10 years. It's a mental thing."
