yes thats true. Really the coach should be teaching a system and have there students progress through the system incorporating the boxing training into it. Kind of like the Ingle system. Learning right execution of techniques and drilling responses, movements etc.. That takes a really well educated coach with a vision of his finished product and knows how to teach. That is not an everyday thing where can encounter a coach like that. Jacksons Gaidojutsu is a precursor like that... They were at the top of MMA for awhile.
