I really think Chris Johnson is the player you have to cut in this instance. It hurts, and he desrves to land onto another NBA team with minutes, but just think about it this way--
if Gordon gets hurt, we have Joe. If Hood gets hurt, we have Burks. Ingles can increase the minutes that he plays relative to the others. Ingles is a very ideal 5th wing.
Meanwhile, if Rudy get hurts, that basically means that we have to play Favors and Bolomboy at the 5 for long stretches. That, to me, is why you kinda have to keep Withey. He provides that length at the 5 and he's already shown being able to fill in for the team and put up some good minutes. He isn't amazing but he's quite cheap for what he offers, and he contests shots well enough.
To me, the cut has to be between CJ, Neto, and Mack. And you gotta go with the one that doesn't rock the boat too much this season, while also protecting the team the most in the long term. I just wish CJ had a three-point shot. Very clearly a smart player.
