Lowry is not 100%. Just look at his play in the first few games to now, especially on D.
Jose is not a part of this teams future in a significant way, he may return as a back up.
It makes no sense to go forward with Jose as the starter. We need to see what a healthy Lowry can do to properly evaluate him, and the team around him.
Jose is a great professional, is very good at what he does, and has some glaring holes. There's nothing wrong with that. Lowry has shown in all likelihood he is the better option long term. We know what Jose brings, we have to see what Lowry can and playing hurt does not seem to be the answer right now.
