Janitor, I'm not sure. There is no film on Hart, and Burns seems more consistent in the ring results and news reads. I do think Hart, because of his greater size matched up better vs. larger heavier in comparison to Burns. I also think Hart lacked skills, and was essentially a very game and competitive man with a decent punch. I tend to think Hart was a lot stronger than he looks in the clinches. Adam would be better qualified to make this call on who he would have favored leading up to the fight. I do. I think Hart is Burn's best win. Johnson, when matched vs top level opponents his size, and near, experience lost three times. See Hart, Choynski, or Griffin. I think Johnson improved a lot by say 1907. I also think the people Johnson fought who had near size or experience post-1907 were not as good as those who defeated him previously.
