Kahn boxed decent for a few rounds but that's about it. Canelo was outboxing him by the end of the 4th. The 5th you could clearly see where the fight was headed. Canelo was setting him for that right hand from the get go. Once canelo figured out the handspeed it was a wrap.
Well... yeah. I think the point Tua is making is that Con fought a better fight than Charlo.
Jermell didn't even really get knocked down. He got caught, said "fukk this shyt" , and then took a knee.
