Its all in the title. UFC grew 'big and strong' since UFC 1, became a well regulated (to some extent) and almost a safe sport, arguably top 5 in the world and its extremely impressive. Nevertheless, I cannot help but wonder if it still was an Open Weight, not time limit, 1 day tournament - would it make any difference? As in would it be undoubtedly Stipe > Jones Adesanya > Khabib and Usman > Volk? Do you see anyone like BJ Penn making it competitive against bigger guys (like Machida) or like Andy Hug laying waste on bigger opponents with ease... Do you think Shevchenko would have a chance vs Gabi Garcia?
