The 49ers just made a terrible mistake.
They agreed to terms with free-agent linebacker Kwon Alexander, and reportedly will pay him $54 million over the next four years ($13.5 million per season). Alexander will earn $27 million guaranteed — tied for the most guaranteed money among inside linebackers with All Pro Luke Kuechly. Alexander now is the second-highest-paid player on the 49ers in terms of average annual money after Jimmy Garoppolo.
Alexander, 24, is a former fourth-round pick who played the first four seasons of his career with the Tampa Bay Buccaneers, and missed lots of tackles.
