As someone else said you are reading lots into one quote earlier this year. You are not in the Padres dugout or locker room so you really have no idea what goes on. There are not many Latin players who are vocal leaders because of the language barrier.
You are trying to find a flaw with him to say he is not a leader. You said he was a glorified DH. So I am reading. Was that a compliment? Sounds like you are saying he will not be worth the money. He’s still just a kid. He has a good time playing the game. How old is Soto now and at what age did Ovechkin become a leader? Quite a gap there I believe.
He's a DH-only who doesn't appear to bring you anything in the clubhouse (not a negative, but not a guy who's leading the team). He's one of the best hitters in baseball but if he's racking up homers in 85-win seasons then what's the point? My point is that when you invest half a billion dollars into a player, you kind of hope he can be the tone setter in the clubhouse and deliver championships, and to do that so many things need to be right.
With Soto I think you need to realize he's (probably) never going to be a rah-rah guy or the silent leader and is more the "have fun and smash" guy and adjust accordingly. He was perfect in 2019 as a young player because that team was 90% bits and 10% proven veterans who set the tone and he could just be himself. Not every player is going to thrive running a clubhouse, and to *me*, that is a knock at his contract demands, but he'll still get paid big time and deserves it based on his production.
If the Nats were signing Soto long-term I'd make sure we always had veteran pitchers who can run that side of things and 1-2 veteran hitters who can handle running the clubhouse and let Soto just smash every day. I think the Padres wanted Soto to come in and be the GUY in the room and instead Machado has free reign it sounds like and the clubhouse sucks ass and the results speak for themselves. A good GM and good manager can overcome this easily but the Padres appear to be idiots. Two of their biggest investments are in Machado and Tatis, two certified morons.
I think clubhouse vibes are really crucial overall if you want to over-perform your expected every year. Davey is a whatever manager but the vibes around our team have always been rock solid and players clearly enjoy playing here. Everyone in San Diego looks miserable. That matters.
