As we endure the annual, mind-numbing boredom of NFL pre-season football, my thoughts about football are elsewhere.

That is, why on earth do NFL teams expose their valuable players to such extreme risk of injury when the games do not even count?

The local Texans lost their first second round draft choice to injury for the season this past weekend. And for what?

The elephant in the closet in regard to football overall and the NFL in particular is the increasing recognition of the high injury risk that players are taking. Although this NY Times article involves primarily former MLB star Lou Gehrig and speculation whether he really died of amyotrophic lateral sclerosis, the article provides an overview of new clinical evidence that the brain damage being suffered by NFL players is severe:

Doctors at the Veterans Affairs Medical Center in Bedford, Mass., and the Boston University School of Medicine, the primary researchers of brain damage among deceased National Football League players, said that markings in the spinal cords of two players and one boxer who also received a diagnosis of A.L.S. indicated that those men did not have A.L.S. at all. They had a different fatal disease, doctors said, caused by concussion like trauma, that erodes the central nervous system in similar ways.

The finding could prompt a redirection in the study of motor degeneration in athletes and military veterans being given diagnoses of A.L.S. at rates considerably higher than normal, said several experts in A.L.S. who had seen early versions of the paper. Patients with significant histories of brain trauma could be considered for different types of treatment in the future, perhaps leading toward new pathways for a cure. [ . . .]

A link between professional football and A.L.S. follows recent discoveries of on-field brain trauma leading to dementia and other cognitive decline in some N.F.L. veterans. Dr. McKee and her group identified 14 former N.F.L. players since 1960 as having been given diagnoses of A.L.S., a total about eight times higher than what would be expected among men in the United States of similar ages.

However, the doctors cautioned, the existence of the increased number of A.L.S.-like cases should not create the same level of public alarm as the cognitive effects of brain trauma, which affect hundreds of former professionals and perhaps thousands of boys and girls across many youth sports.

Although even players commonly continue to underestimate injury risk in the NFL, my sense is that such miscalculations are being understood better and will likely recede. With NFL teams facing increasing litigation risk from injured players, will NFL teams be able to use the shield of the collective bargaining process much longer to protect the league members from the possibly severe financial implications of that risk?

And if the NFL is facing potentially dire financial implications from the increasing recognition of high injury risk, what about the implications for college football, where the compensation paid to players is regulated more rigidly than in the NFL?

Finally, will the financial implications of injury risk in football eventually prompt dramatic changes in the way the game is played?

Seems to me that these questions are a lot more interesting than pre-season football.
