I agree that Harden got greedy. Houston is a train-wreck. The GM has no idea what he is doing. He runs the team like it is a monopoly (buying a property and the then selling it). Harden is going to wish he had just accepted the $55 million contract once he starts losing 50 games a year in Houston.
I think OKC has strengthened their bench and if Lamb is worth his lottery selection then I think it is a great move for OKC. I am 50/50 on Lamb as an NBA player but I haven't see him play in the NBA so I will hold off with any final judgment until I see him play a few season in the NBA.
I think OKC did the right thing. You have to do what is best for your franchise. They made a decent offer and now they have moved on. I think the Jazz can keep their four core guys if they are smart and don't overpay for other free agents. If Harden fails in Houston he will become the poster child for all franchises when they negotiate with their players. Hopefully, the Jazz will have a championship caliber team in 2 years to remind their young players about taking a little less money to play with a team who can compete for an NBA championship.
I hope the Jazz are talking with the kids about re-signing sooner before they are in their contract years. However, very few players are irreplaceable. Sometimes you have to cut your losses and get the best deal for the franchise like OKC did.
This cuts both ways. If Harden was greedy for wanting another 5.5 million and was foolish for going to Houston, the same can be said for OKC. To me it looks like they have given up a key part of their team to save 5.5 million, and they may regret when they get bounced out of the first or second round. Both sides were foolish.
