Why does buddy always fall victim to the cycle?

Why does he so consistently ball out for the first 20 then durastically drop off, the dubs being built around getting the greatest shooter oat open shots, you’d think buddy would be able to be a perfect plug and play for the system, but what about him makes him so consistently dookie? And is there anyway to get him going again? Just feels like such a waste to a perfect opportunity. to just accept he will forever fulfill the assblaster cycle
