"I don't buy into '30 and you're old,'" said Allen, who turned 31 in April. " ... But I do feel like I'm back there. I feel that's where I'm at mentally, physically, and I feel like we have a team that can even make it better."
While Allen, with 117 career NFL sacks, believes he can get to 23 sacks in a season (he had 22 in 2011), he doesn't plan on sticking around to challenge Bruce Smith's career record of 200.
"You've got to average 10 sacks a year for 20 years or you've got to average like 15 for (13 or 14 years)," Allen said. "The numbers are tough. When I get to that point in my career to where they're like, 'Well, we think someone else can do it better every single down,' I'll graciously step aside, enjoy my family and raise kids."
