Imo the main drop offs are jump shot making and defense. Jamal Murray is an elite shot maker and has basically every jump shot in the book, pull up left / right, catch and shoot, fadeaway left / right ect ect ect. He has enough size at the guard position where it’s tough to force him out of his comfort zone shooting. The size is what helps on defense also.

As a number 2 next to jokic his shot making ability is what makes him the perfect fit.
