I'd say without question Berry's draw was tougher than Kral's - He had the most trouble (save the finals) with the Princeton kid and after that, his opponents had a combined 2 losses (prior to their match with him) and half of those losses were Sliga's closest match of the season.
IMHO I think Sliga could have beaten anybody at 220 -- I don't know if I would say he could have wrestled an entire tournament giving up that much size and not been too worn out by the the last match, but in a single match situation, I do think he and most likely Berry could win.
But all we can say for sure about 220 is that Kral is the champion and that cannot be taken away...
