This dude is a true lucky champ, Teofimo was legit sick and going through serious personal problems before the fight with Kambosos, his spiteful older wife took the baby and demanded a divorce, his mom and sister warned him not to marry a Divorced older woman but he refused and now he paid the price.
Kambosos talked so big against Haney thats all this dude can do is toot his horn, looking at how small his bone structure is no wonder he cant hang, dude got skinny wrists, ankles and small fist and feet, he belongs at 122 or 126 pounds, but the problem is his metabolism is slow he said he has to diet to stay slim because he was a fat kid.
If you look at Manny Pacquiao he might be short but his bones are big, he has a dense bones structure big hands, feet, ankles, wrist and big square head and jaw this is why he was able to handle power of men who weigh 170 or 180 in the ring, if you bone structure is not dense you cant hang with bigger guys unless you are a masterful defensive boxer like Floyd Mayweather, and Kambosos is not a master defensive fighter.
So he might as well retire, and do commentary or something. Because if he really thinks he can go to 140 now and be a champion or compete he will be in for a shock, he will get knocked cold, look at Teofimo at 140 he looked ordinary.
