Bills (4-1) at Chiefs (4-1)

■ Time: 1:25 p.m., KLAS-8

■ Line/total: Bills -2½ ,54

■ Analysis: Many believe revenge is a big factor in this game for Buffalo, which suffered an overtime playoff loss at Kansas City in January after it took the lead with 13 seconds left. Others believe that the Chiefs have a psychological edge in this one because of that victory. But the Bills spanked Kansas City at Arrowhead Stadium in the regular season a few months before losing that playoff matchup. I believe QBS Josh Allen and Patrick Mahomes will play well. But the big difference will be Buffalo’s superior defense, while Kansas City’s pass defense has been vulnerable. I’m not crazy about laying points on the road at Arrowhead. But with the line less than a field goal, I have to side with the Bills.

■ By the numbers: Kansas City is 0-4 ATS against the AFC. … The Chiefs are on a 1-4 spread skid following a straight-up win.

■ Pick: Bills 31, Chiefs 28
