Those experts are picking the Lakers and OKC over Spurs because they look at the Tremendous amount of Talents. ala Lakers have Kobe + Nash + Howard + Gasol... or OkC who have Durant + Westbrook + (Ibaka will make the All Stars this year imo). i.e. on paper those two teams look pretty darn good.
Digging deeper than the veneer as Hollinger did, one would see how the Spurs have all components to win it all albeit Spurs need to be better defensively and that would happen when we get all our guys healthy.
I am more surprised how no love for the HEAT or for the Knicks...
