He's not as good as he used to be, he should retire, srs, same thing with Jose Aldo
I don't think Max has lost anything, he's as good as he's ever been, it's just that better fighters have entered the picture.
Everyone loses eventually, even Mike Tyson. That's why it's good to not get too cocky when you're on top and Max has always handled himself in a classy way. The Hawaiin fighters are mostly a classy bunch and don't talk a bunch of crap.
