I would think 15/16 when we won the Championship under Dyche runs it close, we only lost 5 games all season, and while Brighton and Boro hung onto our coat tails until the end, we were 24 points clear of the 7th placed team. We lost at Hull on Boxing Day, there were 23 League games left, half the season to come, we didn't lose any of them, 16 wins, 7 draws, that was some domination.
