The San Francisco 49ers wild offseason featured a handful of retirements, the most surprising of which was probably linebacker Chris Borland. The soon-to-be second year linebacker announced in March that he had decided to walk away from the NFL due to concerns about head trauma.
The announcement came via ESPN's Outside the Lines, and that announcement was part of what is now a broader article about Borland's decision. Steve Fainaru and Mark Fainaru-Wada, two of the best investigative reports on ESPN's payroll, followed Borland around for five months and put together an all-encompassing article that published on Thursday.
