I'm sorry, but this just isn't true. For any given game, each team has just one. But some teams have the same guy starting the vast majority of their games and some don't.
If you want to go through each team and select their "starter", be my guest. But I wanted to paint the picture of what a starter-worthy player looks like so we'd have some basis for the conversation of whether a certain offensive line qualified a player to be a starter. And you don't get to that picture by including fill-ins and back-ups.
I got my data from Fangraphs. What's funny is that the differences are pretty much the same whether you include the starters or not. LF is about .35 points higher than CF. RF is about 50 points higher. Some years it's 40, some 60. You can split starters out from backups. Whatever. The point is that corner OF don't hit a ton better than CF.
