I disagree. If one of your big is a stretch the other needs to be a passer. Favors might be the worst passing big in the league.
He consistently made a solid pass to the corner three out of the pick and roll in 2015. I would not call him one of the worst passing bigs in the NBA. I also do not think that is a requirement. You need a physical guy that can bang around and play some post if you have a finesse big. Favors can play around the key pretty well.
This all assuming he is healthy though which is a risk. Which player do you think is a better fit with Porz over Favors that attainable or the same age and level of player?
