These teams met in Week 4 with SD winning 37-20 and covering as a 2.5 point favorite. KC committed 6 turnovers and 9 penalties, which eliminated any chance of winning. But they moved the ball well, and the game would have been closely matched without KC’s repeated mistakes. Since that game, SD has had two 2H collapses against NO and DEN and lost a weather game at CLE to make them 0-3 SU and ATS. In other words, they have given no indication that they should be a 2-score favorite against any NFL team or that they are any better than they were in Week 4. KC is not a good team, but they should stay within the 8.5 point spread here.
