The weight and strength for sure has made a difference, but he seems to be set on staying in the post or camping out on the line on each possession. He never brings his defender out of the post with him where it would be mismatch.It seems Love struggles a bit when teams play really physical with him. Personally, I really think he lost a good deal of strength when he cut down his weight, but maybe that's just me.
Every rule has an exception.
