Just reading this... I'm a fighter caught up in this whole sort of mess. From a fighters standpoint it gets annoying. I like my main coach. We have been together for a while and have won all of our fights together. I had a similar situation 2-3 months ago. Now 1st as a fighter u wanna make sure u are respectful to ALL coaches that are apart of your gym. With that having being said as a fighter it is MY choice who I train with. Just cause a guy comes over and says "hey i have a way to make ur jab faster" does NOT mean i have to go with the guy. Next if your fighters are old enough to know what they want outta this sport they need to have the nerve to say "i'm good man my coach & I already worked on that". The fighter has to stand up for himself @ some point. Now if there are kids envolved then as their coach you should say hey man give my fighter some space. Let Him/Her and the parents make a choice. I'm turning pro next year & dont have time to play those trainer games. Stand up for your guys!! "Jab First... Jab often".
