Agreed. It was my biggest qualm with Ime, but with him there was very little quality depth left after the trade deadline. With Joe, we have legit NBA guys who could play. Hauser, Muscula, Pritchard, even Grant was outside of the rotation for much of the playoffs.
It's a failing. It burns out the top-8, and if the top guys aren't performing (for instance, playing with a torn tendon in their shooting elbow), then nobody is ready to take their place.
