I honestly have no clue how you've come to this conclusion? He has two seasons being over .500 as a manager with one of them being 82-80. And the talent thing doesn't hold weight either because he had a pretty talented roster here for 3.5 years before they decided to dismantle it. He's not good at all. I really don't understand your defense of him? Just baffles me.
World Series win with one of the worst bullpens in playoff history.
And this team didnt have crap for talent after 2019. Corbin imploded. Sanchez became a 6+ ERA. Strasburg is gone. They replaced Rendon with Eric Thames. This team was Scherzer, Turner, and Soto and filled out with Triple A fodder. He had a month in 2021 where he had a healthy, somewhat talented team. Outside of that, this has been one of the least talented franchises in all of baseball.
Through all that, Martinez has kept the locker room. He's got guys still motivated and playing hard. There isnt going to be a better manager than Martinez in DC. No one is turning Lane Thomas into an all star, or fixing Corbin to regain 2019 form. No one is coming in here under Rizzo and getting a different result. And I doubt anyone is coming in with 2019 and winning a WS.
