I was never under any illusions that Bowman was a goal scorer. He was a starter (and deserved his place) because he worked well with Moult, and Moult was scoring the goals. He worked well with Main for a while too, but while Main isn't scoring there was never any chance of Bowman filling that gap. At the very least Main needs to be rested until he finds his form. Arguably, they could both be dropped, but we don't have any other tested combination, so our options are limited there.
