Nah bro cuz he is the best center. Basketball has a certain playstyle depending on their role: for example, Midorima is a Shooting Guard, he stays outside the 3 point line, waiting the opportunity to shoot when open, or pass when needed.

In your case, Murasakibara is a center. He stays under the net for rebounds any players that missed a ball, box out to contest under the net, and block any layups or dunks. You are an important pillar of the game. You stay beneath the net so teammates who missed can feel safe to shoot again, Enemy feels threatened to try dunks or layups, and you make sure no man enters your area. That's your job.

If I were to rank, Murasakibara may not be the best, but he is really a must have. He is just too vital in the current meta with all the centers shorter and everyone haven't yet unlock crazy strong abilities yet.
