Don't see anything wrong here. He isn't saying omfg jones almost got knocked out. He was recognizing a flaw in Jones' last fight that almost costed him the fight.
This. Hes mentioning it for JBJs benefit, to make him more aware. I recall the overhand right, it would of knocked him out I think, IF it hit, but it didn't. JBJ did just enough, it was probably just a little close for comfort for Winklejohn.
Slightly off topic, if people say, why are you mentioning GSPs loss to Serra, it was so long ago, people really should stop mentioning Shaun Salmon. He was fat. And he got KO'd. Long time ago.
