No catcher is an everyday player. Before this year started, no catcher played more games than Grandal between 2018-2020. So I guess no catcher is good or an everyday player.
And no, I'm laughing at you comparing Grandal and Zavala at any level; using W/L record for an individual player in baseball is about as pointless as it gets. Grandal has been the toughest guy to replace on the roster.
Anderson hasn't been hurt for an extended period of time, and outside of you making up a Moncada injury he also has not been hurt or out of the lineup for an extended period of time. Among Robert, Eloy and Madrigal, Grandal has been the hardest person for this team to replace and it has impacted them both defensively and offensively. Your obsession with trying to convince the world that Grandal is bad is odd, and even more odd given what we've had to watch at the position the last 6 weeks.
Oh, and McCann is awful. He was benched in NY because he was poor defensively and offensively. You still stanning for him over Grandal is another joke.
