This 38-year-old NFL vet is still going strong as he is in the midst of his 14th season in the league. It’s clear his dedication to the weight room and his body is what has propelled him throughout his long career. The hard work seems to be paying off, being that he has already racked up five sacks on the year, which was his total for all of last season. #92 will be back on the field this weekend against the Buffalo Bills.
