I just picked up this piece off of the official sites Chalk Talk.
After limiting the 49ers to just 161 total yards Sunday, the Bears defense leapfrogged the Bucs and Ravens and now ranks No. 1 in the NFL. Chicago is permitting 253.7 yards per game, just ahead of Tampa Bay (253.8) and Baltimore (270.9). The Bears also lead the NFL in fewest points allowed with 107 and haven't topped the league in both categories since 1986.
