I currently go to MMA gym with Muay Thai, Boxing, and Jujutsu. The boxing coach has slightly different advice: wants me to utilize a slightly square/wider stance below (eg Mike Tyson and others used). One thing I learned, everyone has different body type features, so one adjustment won't work for others. No one wants to switch gyms because of one boxing coach, when the other Muay thai and BJJ instructors are great. The boxing coach is great himself (has unique advice sometimes).
How does student respectfully disagree with a coach/sensai while keeping respect in the gym? A change in my stance, makes athlete redo rhythm, spacial location, flow for my punches, it just misaligns person's game. Disagreeing with a instructor at a 'dojo' and refusing to take the advice can get athletes snubbed. So want to be careful. I feel like saying, "well my last boxing coach or the internet resource talk about" however for some reason that sounds silly or seem like really wouldn't care. And at the end of the day, the guy could kick most anyone bu-- in a boxing match. The strongest of men have the highest of egos. I should tell him hell with the advice and man up, but better to deal with things in life diplomatically. Any advice from coaches or pro expert students would be great.
This is just one piece of advice different, along couple others. I brought the issue up once casually, he tends to disagree.
Boxers with a square stance eg: Tyson, Julio Chavez, Floyd Patterson https://forums.sherdog.com/threads/is-anyone-here-a-square-on-boxer.4104647/
