So you are stating that the reason Devers refused to play first base was because he watched Arroyo in right field and he watched Franchy at 1b? I’d be absolutely shocked if either of those two entered his mind. He didn’t say “I’m not going to first because I’ve never played it before and I’m uncomfortable.” But he did say “do they expect me to play every position?”
That sounds more like a man just sick of being moved than a man worried about learning to play 1b. And if it was done for no reason, it becomes more understandable. But it wasn’t. And if the argument is “Breslow should have gotten someone better than Toro in the off-season, thats actually not realistic. Any backup 1b signing on to be a backup is going to be Toro-caliber or worse. The ceiling in that room is Rowdy Tellez.
On the other hand, the Sox did have a serviceable DH in Yoshida coming back that needed a place to play. At 5’4” or whatever, he wasn’t an option for 1b, although he reportedly practiced it without whining. And getting both in made the best Sox lineup with their current roster.
I believe Devers was upset at being removed from 3b, and didn’t care why he was asked to move again. He probably felt disrespected, and frustrated. And not because he watched Franchy struggle at 1b…
