That is true you do see a lot of trainers mold their fighters into one style but...What you see isn't always what you get.....You used Cus and his guys for EG..Tyson and Floyd had the patent Peek A boo style taught by Cus but just because it worked for them doesnt mean every fighter can use that style..Even if he knows it perfectly....That style is meant for shorter fighters...It helps them get in close and do the damage where they are most effective...Tyson and Patterson both had short arms...They needed to be in closer against bigger men...The bob and weave is to avoid the punches the jabbing in is to keep the other guy on offense on the way in then they go to work ...Body head hooks uppercuts is the main arsenal opf that style...Not good if you are 6'5"...A good trainer knows if his style is right for a guy...You just see thew ones who master it...a really good trainer adjust styles according to the fighter...Not the fighter to his style
