If there is one constant between all the NFL owners, it's this: You can always count on them to screw with the health of their players

At least a half-dozen top NFL health officials waged an improper, behind-the-scenes campaign last year to influence a major U.S. government research study on football and brain disease, congressional investigators have concluded in a new report.

The 91-page report describes how the NFL pressured the National Institutes of Health to strip the $16 million project from a prominent Boston University researcher and tried to redirect the money to members of the league's committee on brain injuries. The study was to have been funded out of a $30 million "unrestricted gift" the NFL gave the NIH in 2012.

After the NIH rebuffed the NFL's campaign to remove Robert Stern, an expert in neurodegenerative disease who has criticized the league, the NFL backed out of a signed agreement to pay for the study, the report shows. Taxpayers ended up bearing the cost instead.

Never, ever mess with the NFL's desire to make money. Not even if your brain is being turned into cream corn.
