I was having an arguement with a buddy of mine about trainers...He tried to say that the trainer does not matter...once the fighhter knows how to fight the trainer is just there more or less for workouts etc....

I tried to argue the fact that many of great fighters have been brought to new levels by a great trainer...and explained the importance of certain trainers knowing how to get the most of a fighter...

He continues to disagree...Just wondering what some of eveyones opp is on how important a good trainer is for a fighter at any level be it on a physical or mental level
