I don't know, I am not putting too much faith into the Dolphins either. They could lose to Buffalo or the Jets too. I mean, they already lost to the Bills at home earlier this season. And now they have to play them in Buffalo. The Jets could go either way too, and division games are never easy. The Dolphins didn't help themselves much by losing to the Bucs either.
I am hoping the Ravens take the last spot. We will be really lucky if we do make the playoffs. I am honestly not that worried about the Lions this upcoming MNF. They are an underachieving team with a great offense, but their coaching is horrible. Plus, the Ravens offense is better now with Pitta back. It will be a close game, but I think the Ravens will win. The New England game will be interesting, but they are missing Gronkowski again we have their number lately. The Bengals game though will be tricky and they will be playing tough for a first round bye. They are the most likely team we will play too if we make the playoffs.
In the end, the last playoff spot will come down the Ravens, Chargers, and Dolphins.
