Arroyo has not proven he is a starter, but that’s not even remotely the same as proving he isn’t one.
One might think a fan who has spent the last few seasons in watches Luke Voit, Gio Urshela, Aaron Hicks, Mike Tauchman, Didi Grigorius, etc. might understand some players are later bloomers.
Unless, like everyone else, he knows those players only bloomed late because they cheated...
