I don't know why it took the Nats so long to figure out the bullpen issues. The solution was obvious by mid-May. They needed to go into the 7th inning with an eight run lead to have a chance of hanging on to win by one or two. I don't know why Davey didn't figure that out a lot sooner. The trades at the deadline helped some, but the bullpen will still probably be their undoing.
The other thing to remember about playoffs is that you don’t need 5 starting pitchers, you need 2 killers. You can have one pitch the first game, the 2nd, then a travel day, use another pitcher the next day, the let them pitch again. They can pitch on three days rest and pitch four out of five games in the series.
