I would grab Murphy. If he actually gets minutes after the trade, he's going to be solid and a massive steal.
Favors hasn't looked that great even starting now, and I'm not convinced he would gain any touches in Denver. His major issue is foul trouble limiting his minutes.
Minutes? even with Maxiel and CV31? He was a atrocious this season when he got minutes. he is shooting less than 40% from the field. His FT's are even off. Favors would be the better choice if you need some blocks and rebounds
