I think Burrows has shown enough technical ability to play other positions. He played a couple of games in centre midfield last season, and although didn't do great, based on what we've seen this season he was no worse than 2026 Arblaster and most of Rothwells appearances...
I think it's a very narrow-minded view to think a player cant play other positions. Based on your logic because Len Badger didn't work a thousand years ago, we should stop experimenting. It's not like we are endowed with great players and McCallum is a better LB than Burrows. I'd rather Tufty earned his money and found a way of getting the best players on the pitch then we had a very binary outlook.
In terms of Burrows being a 'winger' I'd argue he's more of an old school LH in the same mould of a Beckham. He had a semi-decent career despite never having the pace or skills to run past a FB....
Like I say, it's a very binary mindset to have, and with our budget next season, we need to find creative ways to get our best players on the pitch.
