I can do everything you said with my left except write and throw a football with my left
Can dribble and finish at the rim often with my left
My left hand’s not weak, it’s just not my dominant hand, my right is powerful; I’ve been in street fights where I’ve punished someone with my right
Naturally I just fight with my right dominant because it’s easier for me to pivot and move off my right
Try to explain it to bruh but he hell bent, might just ask him to spar respectfully
Ok cool.
Sounds like your left is pretty solid. The thing is, there is nothing wrong with developing your left side more either. You should be able to pivot equally on both stances. If one is much easier, than the other side is still under developed.
Bruh might think you're too dominant with your right hand and wants to balance you out.
I wouldn't ask him to spar yet. Ask him to do the mitts a few times while your southpaw. Let him gauge your power and movement that way. If he feels that your shots aren't the of the same caliber as the conventional stance, you might wanna stay conventional a lil longer.
