Regarding 2015 -- let's not rewrite history. He was out of this world until mid-August. His productivity dropped precipitously just when he was needed most.
Huh, what the hell does that mean? He went 9/33 on a 10 game west coast road trip with a home run and a couple of doubles and that "slump" cost the Nats their season. Nevermind that he hit .341 in September with 10 HR and a 1.244 OPS when I guess it didn't matter? The mental gymnastics people go through to discredit his production as non-clutch is so over the top sometimes.
