In a column last week, conservative pundit and global warming denier made anuncharacteristic display of compassion for professional football players, explaining how the changing nature of the sport endangers players’ long term health:

Football is bigger than ever, in several senses. Bear Bryant’s 1966 undefeated Alabama team had only 19 players who weighed more than 200 pounds. The heaviest weighed 223. The linemen averaged 194. The quarterback weighed 177. Today, many high school teams are much bigger. In 1980, only three NFL players weighed 300 or more pounds. In 2011, according to pro-football-reference.com, there were 352, including three 350-pounders. Thirty-one of the NFL’s 32 offensive lines averaged more than 300.

Various unsurprising studies indicate high early mortality rates among linemen resulting from cardiovascular disease. For all players who play five or more years, life expectancy is less than 60; for linemen it is much less. . . . [A]ccumulating evidence about new understandings of the human body — the brain, especially, but not exclusively — compel the conclusion that football is a mistake because the body is not built to absorb, and cannot be adequately modified by training or protected by equipment to absorb, the game’s kinetic energies.
