Thank goodness he didn't sign with the Pels. Two years ago he was arguably the best center in the NBA. He is so toxic right now and even if someone does sign him, it doubt he gets the money that his talents justify.
I think a lot of it is also based on the fact that he looked mostly not very good in the finals and was hit or miss when he came back. To many questions about long term affect of the injuries on top of his toxic personality.
