I don't believe him. It's part of his narcissism. His self esteem is so low, he can never be wrong and it also makes him act grandiose to compensate. He will never be wrong. Preferably it's someone else's fault but if not he's just kidding.
I don't know about other teams but the players seem to have completely bought in to what Harris and Hinch have asked them to do.
Another thing I noticed is they seem to hold themselves accountable. I'm not sure if it's an individual thing and leading by example or if guys are vocal behind the scenes. That's something I've heard many times over the years about the '84 team. They held each other accountable and it elevated everyone's performance.
I'm still reeling from The Last of Us because I didn't play the games. Not sure I can handle this much drama in one day. I'm having terrible, shocking visions of Maeda pitching.
