Jimmy Simpson could have had a hat full of wins had the machinery been able to stand his hard riding, first rider to break 60, 70 & 80mph barriers, class!!
Also Harold Daniell won pre ww2 and twice after it, probably could have challenged the then all time best of Stanley Woods (10 wins).
But in modern era I think DJ would have gone on to challenge Joeys tally, he just made it look so easy to win around here.
