Chiefs running back Jamaal Charles estimates he's 80 percent recovered from a torn ACL in his left knee and will be back with a vengeance in 2012.
Charles, injured Week 2 at Minnesota when he landed awkwardly, was an All-Pro in 2011, rushing for 1,467 yards in a timeshare with Thomas Jones.
"If you're worried about me not being the same, just look for this year, look out for me and you'll see," Charles told KCChiefs.com.
This season, the Chiefs are pairing Charles with newcomer Peyton Hillis, who signed as a free agent in the offseason.
Charles has dropped weight being away from the game for eight months. He won't be pushed in offseason workouts or training camp, but he's ready for whatever coach Romeo Crennel clears him to do.
"I feel like I can do the same things my teammates do," Charles said. "I do it without the coaches around. I catch balls, I cut, I do ladder drills and I've been doing this for like two months. So coaches weren't there when I was back home working out, so whatever time that I need for my body to rest, I think it's even better to wait it out for awhile."
