Make any player on Denver prove you wrong. The Seattle defense is incredible, and their willingness to cede some yards and points up by multiple scores is making some folks optimistic about this Broncos team. Smith-Njigba might clear 89.5 on three receptions. Don’t sour your weekend thinking this is the one Denver’s offense awakens.
