I'd completely reverse this. If Barnsley go up, it's a triumph of smart management and intelligent use of resources.
What's embarrassing is that to do well in the Premier League it now seems that a team needs billionaire backers.
If Barnsley should get promoted on their merits, by being one of the best teams in the Championship, but subsequently sink without trace in the Premiership, as they well might, then the problem isn't with them; it's with the gulf that's been created between the divisions by the vast amounts of money sloshing around at the top.
Until something is done to make this more equitable, then any team that goes up (including maybe, one day, us), is likely to struggle.
