Former San Francisco 49ers linebacker Chris Borland retired from the NFL after just one season. A second-round pick of the team back in 2014, Borland started eight games and recorded 107 tackles in his only season.

The Wisconsin product stepped away from the game in a surprise announcement after his rookie campaign. The primary reason for a then 24-year-old linebacker giving up nearly $3 million in guaranteed cash was concern over his long-term health.

Now, in joining multiple former NFL players in criticizing the league’s handling of Chronic traumatic encephalopathy (CTE), Borland just recently took part in a public service announcement (PSA) put together by the Union of Concerned Scientists.

And it’s interesting to say the least.

“For many years the NFL denied the linke (to CTE). Unfortunately, the NFL isn’t the only powerful players that’s sidelining science,” Borland said, via PBS’ Frontline. “Lobbyists in many different industries are paid handsomely to concvince lawmakers to undermine science that protects our health.”

The Hollywood blockbuster Concussion starring Will Smith as Dr. Bennet Omalu showed exactly how powerful these lobbyists can be. Some of whom worked on the behalf of the NFL to call Omalu’s research junk science. Remember, he’s largely credited for inventing the theory that’s now known as fact, CTE.
