not entirely true.
what i agree with is that you're making a point about "using boxing techniques and adjusting them to mma". that is correct.
what i am disagreeing on is that, my point is you can't use all boxing techniques and be as effective in mma. some sacrifices need to be made, and when doing drills, which create muscle memory, there's boxing techniques that you simply can't allow to be drilled into your habits.
@ifindgifsforjackslack gave some examples which are very valid, and i'd like us to tackle them just as examples, not as the be-all-end-all principle of this discussion. slipping a punch and ducking or weaving is not as safe to do in mma as in boxing because of knees, so when drilling, you can't just train to slip/weave/bob when being punched. boxers have the luxury of NOT having to drill leg kick defense, or sprawls. when mma fighters need to incorporate those things in what they need to drill,
stances get affected, and distance management, which means that there's simply habits and practices in boxing that will do jack-shit in mma; and mma guys need not pick up on those habits UNLESS THEY WANT TO GO INTO BOXING FOR THE REST OF THEIR FIGHTING CAREERS (in which case it'd make sense that they fully commit to those boxing techniques).
