He recorded 14 tackles and an interception in a 20–16 win in Arizona. He also had a huge game in week 4 against St. Louis finishing with 8 tackles, 2.5 sacks and an interception return for a 23-yard touchdown. The biggest improvement in his game from the previous year was the increased sideline-to-sideline range. Willis made 54 tackles on plays labeled as "Wide left" or "Wide right" which accounted for 35.5% of his total tackles. In that area, he led all inside linebackers by a large margin. He was also the league leader in impact plays with a total of 27.

However, shortly before the Pro Bowl, which was set in South Florida, Willis decided to play it safe and opted not to play due to a leg injury he sustained. He stayed in South Florida for the game and stood on the sideline in support of the NFC team and 49er teammates Frank Gore, Vernon Davis, Justin Smith and Andy Lee. Willis was named the 2009 NFL Alumni Linebacker of the Year, an award voted on by past NFL linebackers. Willis also became the second NFL player to win the Butkus Award since it was expanded in 2008 to include high school and professional winners in part to help end anabolic steroid abuse among young athletes. 2010
