Puka Nacua wants to retire "early"

Chris Borland was a big one I remember. He was very young.
That made me go down the rabbit hole….he did retire quickly and has been an outspoken critic of the game overall. Didn’t realize that, here’s a snippet from an article I was reading:

Borland attended the premiere of GridIron Gladiators, directed by Todd Trigsted on April 19, 2015, in Portland, Oregon[30]Borland has been outspoken about his decision to retire. He has received both praise and criticism for his assertions in many interviews, including one with CBS News in which he stated that he believes football as a whole to be "inherently dangerous".[31]

In a December 2015 Frontline interview, Borland said, "Last year the NFL commissioned actuaries to estimate how many NFL veterans would have brain damage. And the number they came up with was three out of 10. So if I turn on a game, and a third of the guys will have brain damage in life, I just, I can't really support that. And, I don't really watch football anymore. If it's on, I may peek at it, but ..." He shook his head as the video faded.
