Seventeen weeks of preamble led to this. Eight N.F.L. teams will fight for a chance to move on from a wild-card round that features the winners of the last three Super Bowls and that has one game in which the road team is favored. Saturday : Bills/Texans 4:30pm The teams are evenly matched, and while Houston’s home-field advantage makes it a worthy favorite, there is potential for an upset. Titans/Patriots 8:15pm The Patriots are vulnerable to an upset, which might look shocking on paper, but actually would not be surprising at all. Sunday: Vikings/Saints 1:00pm It was only two seasons ago that the Vikings upset New Orleans in the divisional around but that game was in Minnesota. This one is in New Orleans, and for it to even be close would be surprising. Seahawks/Eagles 4:15pm The Seahawks are not the defensive powerhouse they once were, even with Clowney on the field, but an offense led by Russell Wilson is good enough that they should be able to get through to the divisional round.
