49ers general manager John Lynch acknowledged that he signed Kwon Alexander to fill the void left by former 49ers linebacker Reuben Foster, who was released last season. 

In an interview with 49ers.com, Lynch spoke about how he and his staff brought back several familiar faces to the linebackers room. He was also very frank about what the team lost in Foster as a player. 

“Let’s be honest,” Lynch said. “We had a void that we thought we had filled with Reuben Foster. Things transpired there. We had a void there and that stinks but you can’t just sit there and pout, you gotta say ‘OK, let’s do something.'

“We needed a dynamic football player at that position. It’s a very critical position in our scheme and this became the guy. Kwon became the guy that we wanted to be that guy.” 

Alexander has many of the same on-field characteristics as Foster. He’s known as a hard hitter who flies around the field, making players think twice about going across the middle. He may make some mistakes in the game, but his passion and heart are recognized by his teammates. 

“I think what stood out to us with Kwon,” Lynch said, “he’s a dynamic football player. He’s a tone setter. You need tone-setters on your defense. 

 

“I think he’s a guy that when you watch him, when you talk to people who played against him, people who played with him, he’s exactly that. His type of play running all over the field, hitting people, getting the ball, it’s contagious. We need that.” 

The 49ers' admiration for Alexander grew as they did more research on him. They understand it may take some time before he returns to 100 percent health.

“The more we watched him the more we liked,” Lynch said. “We knew he was coming off an ACL injury but we got comfortable with the medical part and also got comfortable with 'Hey, we are going to wait as long as it takes.' This is a long-term investment. He’s doing very well in his rehab.” 

The staff ideally would like to see Alexander lined up next to Fred Warner, who had a stand-out rookie season. They also brought back Elijah Lee, special teams contributor Mark Nzeocha, and signed ex-Panther David Mayo to a two-year contract to fill out the linebackers room.
