Sadly, you're right in my case. It's stupid and assinine for me to insist that there aren't two wild cards. I don't think it's stupid for the Nats to set their sites on holding on to first place.
So Eddie, I see that the thread title has been updated to reflect the full array of possibilities. This way, the reader and place weight appropriate with his/her own judgement.
I don't think there's any concern that Nats are focused on anything else but winning the division at this point. No team would put making the wild card play-in game as remotely as valuable as a division title, given the elimination of one of the two teams immediately, a 50% haircut to the overall probability of winning it all.
