I don't get what the concern is (still needing a win ourselves is the obvious concern). But the bengals/ravens game is at 1. The bengals get the 2 seed and a bye if they win plus patriots lose. Since the Pats don't play until 4, they would play to beat the ravens, keep them out and possibly get a better seeding. Plus the colts play the jags at 1.
The bengals have the tiebreak head to head over the colts but the colts have the jags at home and both are 10-5. The bengals would drop to the 4 seed and play the chiefs instead of whoever is the 6th seed IF they lose and colts win. They're gonna play to win, which if Dolphins win and Ravens lose means we're in. If we and Ravens win then we can worry about the chargers. If it doesn't work out the dolphins can only blame themselves. They had 2 games to play and completely controlled their own destiny.
