Wingers would be but it depends on the type of half back flank, because Sicily has played HBF well and isn't a big runner, while someone like Jiath is the opposite, aswell as Bramble when he played there late last year. It depends on the player.No way man, wingers probably run 5+ more kms per game than HBFs would. Wing would have to be the most endurance-based position in the game, right? Maybe ruck?
