Report: 49ers to sign Kwon Alexander to 4-year, $54 million deal with $27 million in 'rolling guarantees'

The 49ers have made their first big (reported) move of the offseason, inking inside linebacker Kwon Alexander, per ProFootballTalk.

He's slated to join the Niners on a four-year pact worth $54 million, with $27 million in "rolling guarantees."

Alexander, the ex-Buc, tore his ACL last October. His $13.5 million annual salary makes him the highest-paid inside linebacker.
