He is much smarter than me and can easily talk circles around my simple self....but his take is whey is just "waste" for the most part, aka your body is not absorbing or using most of it. BCAAs in his opinion have higher absorption and utilization rate...and you really don't need to take a ton either (assuming you also eat enough whole food proteins).
He has many of his high level bodybuilders/figure models that he coaches using BCAAs more (and less whey) and has nothing but good things to say about the results from it.
