The Kansas City Chiefs might have a perfect start to the 2013 season, but they aren't so perfect against the AFC East.
The Chiefs (8-0 SU, 5-3 ATS) face the Buffalo Bills Sunday but have gone 0-9 ATS against AFC East opponents, including a SU and ATS loss at Buffalo in Week 2 as 3-point road dogs last season.
It was Week 8 of the 2008 season when the Chiefs last covered against an AFC East foe. They coverd as 14-point dogs against the New York Jets, but lost straight up 28-24.
KC will try to snap its ATS funk against the Bills Sunday. The Chiefs are 3.5-point road faves at Ralph Wilson Stadium.
