The NFL's best inside linebackers, No. 3: Danny Trevathan
Between signing the aforementioned Freeman and adding Trevathan, the Bears have rebuilt the heart of their 3-4 defense in one off-season. Initially a sixth-round pick in the 2012 draft (a pick Denver received in the Tim Tebow trade, for you trivia nerds), Trevathan gradually gained responsibility under Wade Phillips thanks to his versatility and reliability. In a pivotal late-season Monday Night Football win over Cincinnati, he stood up to the Bengals' bully ball, bringing down Jeremy Hill and Giovanni Bernard a combined 12 times and earning a +4.7 grade from Pro Football Focus. Three wins later, he showed off his ability to rush the passer and drop back in Super Bowl 50, leading the team with eight tackles and a fumble recovery while helping to limit Cam Newton's No. 1 option, Greg Olsen, to 41 yards and his lowest catch-percentage since Week 4 of the regular season. Now we'll get to see what Trevathan is capable of under Vic Fangio, who built Bowman and Patrick Willis into the best inside linebacker duo in the league during his time with the 49ers. Among the many excited to see what he brings to Chicago? President Barack Obama, who told the ‘backer during his White House visit, "I can't wait to see you play with the Bears."
