Also not a big fan of the scooping parry defense, maidana nailed broner with his left hook for that reaction.
You can bend your knees with him and take it on the elbow then throw back, you can throw a left hook at the same time while turning off, you can step back and let it fall short, you can jab his left hand just before he throws it to disrupt it (and get a priceless look of confusion), etc. really anything to let him know you're not gonna just stand there and get set up. Don't let him feel comfortable throwing it.
I agree that's not a punch you ever really want the guy throwing at you. You wanna make him feel it's not worth it.
