The Sunday NFL Playoff schedule starts with the Buffalo Bills vs. Jacksonville Jaguars at 1 p.m. ET on CBS. This seems like the best opportunity for Josh Allen to win a Super Bowl with the absence of the Chiefs, Bengals, and Ravens. However, the Bills are banged up on defense while the Jags have the best rush defense in the league.
