Mussini would have had a clearly defined role here next season and would have been in the rotation. With that being said I like having my best players on the floor as much as possible and I want Ponds, Lovett and Simon on the floor most of the game. Most good teams only play 8 or 9 guys.
Owens, Ahmed, Clark, Simon, Ponds, Lovett, Yawke and Wilson make 8 so not the end of the world. While you can certainly can say Mussini is way more productive than Yakwe, because he is a big he was going to play more than Mussini who was basically going to be our 9th man.
