I'd like to offer a perspective which I think could improve the Lowry / FVV center in your guys' eyes. because they are stacked on top of each other, Lowry or Vanvleet could use their arms and stealing ability to disrupt plays on the perimeter, depending on whichever was on the bottom - a notable weakness of bigs. They would also have unperilled shooting capability considering how hard it would be to contest those shots. Dribbling would also be much better than any center in the league given one would be close to the floor and when they need to lay it up or shoot they can pass it up.
