How do you figure ?
You not watch the fight / 7th & last round I take it.
From going to the canvass for the 2nd time in rd7 to when the ref had had enough of Joshua 
& waved the fight off - it was around 34seconds 34 !!!  
And at no point Did Joshua show any Sign or intention of wanting to fight on. 
34 seconds !! In his Biggest & 1st Fight In MSG.
Yeah he’d had enough & Quit. 
How do you figure he didn’t.
