Barrow's current average would be the 2nd lowest in League Two right now, think they might struggle when they go up. They will get more away fans, but given their location not a great deal more. They will have to hope they do an Accrington Stanley.
We'd be 5th in League Two with our current average, 18th in League One (but if we were that high we'd be getting at least 1k more even if we were struggling)
