Rose a huge upgrade at PG for the Knicks. They rid themselves of Calderon and his contract. Lose Lopez and Grant but you can't expect to get something for nothing. Also get Holiday (not Jrue) and a 2017 2nd round pick.
I guess the Bulls are doing a total overhaul with the possibility of trading Butler, too.
Rose is a FA after this season, so NYK should get a good year out of him.
All in all, I feel it's really good for the Knicks. Look for them to replace Lopez at C with a big name, too.
