The Dolphins defense is dreadful and has been especially soft over the last three showings. Miami has given up an average of 5.8 yards per play and ranks 26th in EPA allowed per snap since Week 13. What’s more, Miami doesn’t bring much pressure and mixes zone and man coverage in the secondary. It’s notably vulnerable in zone schemes, ranking 30th in team coverage rate at PFF. Purdy is one of the best QBs in the league versus zone defense, owning the No. 1 passer rating against those schemes. As for the San Francisco stop unit, it got key bodies back last week and should be even stronger in Week 16. Dre Greenlaw made his return last Thursday and DE Joey Bosa was back as well.
