As much as people like Harden a deal like this is probably going to be what a team gives up if they get him. Can't see anyone paying more than 70% on the dollar for Harden. He has a team list, he is 31, known locker room problem, and requires special privileges/treatment. Not a lot of options for buyers.
He might promise to buy in with a team and then go off the rails one month in. He could even ask out in a tuff playoff series like Irving. Same selfish approach, same low buy price IMO.
I think Portland makes the most sense. Dallas has the trade chips and is in Texas but does Doncic and Harden make sense?
