CHICAGO BEARS: In his fourth season as defensive coordinator, Vic Fangio is getting the most out of his young unit, much like he did with the 49ers in the early 2010s. With the roster full of budding talent heading into the season, trading for Khalil Mack was the icing on the cake. The 2016 Defensive Player of the Year has been dominant -- and I mean dominant -- with his new team, as he is the only player this season with at least five sacks, four forced fumbles and an INT. It hasn't been just Mack getting sacks or takeaways, though; the entire defense is relentless in getting to the football. That said, it's no surprise Chicago is fifth in sacks (30) and second in the league in takeaways (24) -- including three INTs and one fumble returned for a touchdown. It's found success not only when rushing the passer but in the run game, allowing fewer than 100 rushing yards in seven contests this season. Most importantly, the Bears have stifled offenses for most of the year and are tied for fourth in scoring defense, giving up 19.4 points per game. If they keep this up, they could find themselves back in the playoffs for the first time since 2010.
