The San Francisco 49ers have five outside linebackers who matter: Aldon Smith, Aaron Lynch, Ahmad Brooks, Eli Harold and Corey Lemonier.
All five probably won’t make the team, though. The Niners need no more than four, considering no more than three typically play in a game. But the Niners probably can’t cut any of their top five outside linebackers.
You could make an argument for cutting third-year outside linebacker Corey Lemonier, who has done next to nothing so far in his career. But the Niners spent a third-round pick on him in 2013.
