A straight up trade. What number pick do you think he's worth? 1 2 3 4 5 6 7 8 9+ Worth more than the #1 this year.
Seriously. Nothing else needs to be said. James Harden is a sure thing the rest of these guys are not.
With the big man hurt it would take the #1 plus something else, but that's just me. It's a long shot anyone else becomes as good as Harden is right now and there's atleast a decent chance Harden isn't done improving.
3rd pick, if not 4th. Sorry, but Wiggins and Parker and Embid are excellent prospects that teams will draft and cherish. Not that either will be better than Harden, won't know...but teams will gamble on those guys.
