The Nets get a good bench scorer that will help push for a championship this season

They give up their primary bench scorer for someone who is 5 years younger and putting up better stats

The Celtics get a good veteran scorer that can come off the bench like Dennis did, they would also have Patty for two seasons instead of one, they also pick up Cam Thomas who has looked promising for Brooklyn but is still adjusting to the NBA, he is not helping them win this season
