There are an awful lot of games left. Personally, I have seen too many team's seasons derailed by injuries. Especially in today's age when rosters are not as deep as they have been in the past. I could narrow it to 5-8 teams, but it all defends on how fortunate they are in regards to injuries. The best team doesn't always win, sometimes it is the team that has the ball bounce their way a few times.
If I had to pick one horse, I'm going to pick Appomattox because they are battle tested and have playoff experience. But I wouldn't bet money on anyone at this point.
