I would move the Celtics into tier 2, but overall it's a fair assessment because it looks like he's just evaluating players individually instead of evaluating it like us factoring in the Stevens effect + Smart's contagious ability to rip souls out of opponents.
Btw, you-know-who is Davis, which I believe should be the focal point of a free agency signing after Horford comes off the books (or stays on as a vet min -- please!). I don't see the point at all in trading for him because A) he's not available and never will be B) it's going to cost half the roster.
And honestly, I'm not sure Hou and OKC are solid tier 2 teams.
I have no doubt that OKC is. Their roster is stacked. Westbrook, Roberson (underrated), Anthony, George, Adams (great big). I'm so happy that they're in the West. I think that they have the best chance in beating the Warriors in the playoffs.
The Rockets may not be a tier 2 team because I'm not entirely sure how Paul fits into the Houston Hardens.
