The only reason I would move Beni down in the line up is if Cora thinks that Beni is pressing and that it would take the pressure of off him. I would not do it for a 'numbers' reason.
As professional as the players are, I still think they are mostly creatures of habit and they like consistency.
Someone brought up the point in a game thread about how our players might be out of sorts a bit by having too many days off. I don't know if that's the case or not, but I think it's certainly a valid consideration. I support Cora's decision to rest his starters regularly, but I guess we'll have to see what the net effect is over the long season.
