Reply to comment by Brynmaer in NFL players, especially former linemen, had fewer disease-free years and earlier high blood pressure and diabetes diagnoses. Two age-related diseases, arthritis and dementia, were also more commonly found in former football players than in other men of the same age. by Wagamaga

I would bet it's their diet to maintain the 300+lbs. Most linemen drop significant amount of weight after their playing careers but the extra weight they carry for x amount of years has to take a toll.
