I love what New Orleans did this summer, too, although it was unfortunate that shooting guard Eric Gordon took the fun out of it for Hornets fans with the way he came back dragging his feet after the team matched Phoenix's max offer. Davis will need time to grow, power forward Ryan Anderson and center Robin Lopez were quality free-agent pickups who filled needs, and Austin Rivers was a good draft pick and will be used as a combo guard.
To turn the question the other way, I also like the fact that Oklahoma City didn't mess with its core rotation. Rookie forward Perry Jones and center Hasheem Thabeet will fit in along the edges as long-term projects, but the Thunder maintained their investment in their ever-improving foundation. Their underrated move was to show patience and wisdom, because to make any changes to their core would have set them back.
