J.R. Smith is having a renaissance of sorts playing for the Cleveland Cavaliers - his shooting percentages, points and rebounds per game are all improvements from his numbers with the New York Knicks this season.
This is understandable of course, because as Smith himself said, there's nothing to do in Cleveland except play basketball. One stat not to go up is his assist rate, but with a move on a dime like this on Phoenix Suns guard Brandon Knight, whatever.
