I wasn't calling you an idiot buddy, my apologies if it came out like that. Maybe with top level sparring you might have turned those already great achievements even higher, I have been coaching for twelve years and have guided a number of people though top level fights, sometimes one part of the equation was missing through injury or circumstances, the result was never as good as what it could have been.

Example before I coached Yusaf Mack when he fought Berrio, he was sparring every other day against a high level guys but he gassed out as he was not running. He thought he was training hard but he didn't have the right mix.

I spar with my guys a lot, not so much anymore through injuries but if I went a few week with no sparring, even though I was still training I really noticed the difference, sparring controls adrenaline release, when you get hit your body releases it, the thrill of a fight, the bodies natural reactions to circumstances. Adrenaline is the main cause of guys gassing out, it burns you up, (Nerves, crowd, the fight, getting hit...etc are all to do with adrenaline release) Sparring not only increases your sharpness (So you land with more punches as missing is twice as tiring) but it helps you control your adrenaline. You get a guy who has never boxed in a ring before, he knows the basics and is fit, will always gas out. It takes weeks to eventually get used to it. Your body learns to deal with the release and control it. Sparring even if it is light sparring helps you relax and your body adapt. It is amazing how quickly it forgets, no matter how long you have been doing it or at what level.

Also the nerves of knowing that your preparations haven't gone exactly to plan can also take a lot out of you.

At the end of the day he completed the 12 rounds and won so I am not making excuses, i am just saying if he had sparring he would have been a lot better.
