Yup. When you look at the teams of the early 80's or so they were large physically fit men, not fat at all. Back then our average offensive lineman was around 265-275 pounds. Now what they have done is pack another 35 pounds of fatback on top of what their weight should be, the weight that is...
Getting old,...way old. Every year the same old same old. Modern players are playing at unnatural weights for their bodies. Puts a ton of extra stress on the joints, ligaments, bones, ect ect. Nowhere near as many injuries back in the 70'/80s.
