Doubt must be cast on Tua Tagovailoa following two consecutive poor road performances these last two weeks against the 49ers and Chargers. Miami averaged just 260 total yards and 17 points in those two games. The Chargers' defense is 28th in scoring defense and was without several important defensive players.

I don't see the Dolphins bouncing back on the road against the Bills' defense, which gives up the second-fewest points and ranks in the top 10 in total defense.

Neither offense is going to be helped by the weather conditions with the forecast calling for cold, possible heavy snow and wind in the 15-20 mph range.

These elements take away the Dolphins' most dangerous offensive feature, which is the speed of Tyreek Hill and Jaylen Waddle. Tagovailoa remains unproven in big road games and in cold weather. The Dolphins managed only 212 yards in the first meeting, played in sunny Florida. There were 40 points scored in that contest.

Now the weather has flipped and Miami's offense is at low tide for the first time since Tagovailoa returned from a concussion.
