Doesn't make sense because you refused to listen/read what others were saying, as this has been discussed repeatedly. Bradley will be an unrestricted free agent in a year that was going to cost a lot to retain. Good player, but probably not worth keeping for what he would cost next year.
Crowder is also a good player, but on a very cheap deal for 3 more years. Smart is an ok player who will be a restricted free agent in a year. He's the guy they should have dealt over Bradley, but maybe they just couldn't find the right trade.
Anyway, there were many options for the Celtics, including trading Bradley for a player that cost just enough less that it made the Haywood signing possible.
Utah never had any kind of leverage here. We needed to make a fair offer on Crowder and hope for the best, but Crowder being the best asset of the 3, wasn't going to be given away.
