Where does Andy Ruiz’s technical knockout over Anthony Joshua rank on the list of all-time boxing upsets?

– Fat guys rule.
– Andy Ruiz won by TKO in the seventh round over British sensation and three-belt champion
Anthony Joshua. Ruiz was a +1200 underdog. He’s 33-1 but underestimated because of his pudgy
physique. Ruiz is also the first Mexican heavyweight champion.
– Does this compare to Buster/Tyson?
