I like this trade for Bacon. Although Towns has the potential to be a much better RL player than Monroe, I don't see him being a better fantasy league player than Monroe by any means. Monroe is very productive and reliable, and most of all, proven.
Getting Parsons as a buy low imo is also a great move. Parson stock dropped a lot while he was out, but he's also highly productive , young, and one of the few decent players on the Mavs. He will get his looks and then some.
I'm also of the firm opinion that Clarkson's hype was due to being productive on a poor team. Good job selling high on him and still getting a 2016 #1 in the deal.
I dont understand or care why Donald Sloan is involved, but if it makes any of the two GMs in the deal happy then its cool. He will be on waivers early in the season anyways.
