I think it was a Tim Stillman article that pondered that Ramsdale was being benched because he wasn't doing what Arteta was asking him to do because he was afraid of giving up goals. So it may not be a discussion of quality so much as who is more willing to do what they're told.

It matches both of their characters I think, and Ray's playing may be a message to Ramsdale and possibly the rest of the squad that you listen to the manager or you sit, no matter who you are or what position you play. Then he goes to phrase it in the media as "it's just like any other position, I play the player who makes sense tactically" when what he means is "I play the player that will execute my tactics."
