Portland was great while Roy was healthy, Utah was great before Williams forced his way out, OKC has been good for two whole years, Orlando has been great until Howard forces his way out before the 2012 season. San Antonio is the only good example of late of a lasting small market franchise, their existence doesn't prove anything other than great management and coaching is really important. The same thing can be said of your examples of big market teams, the Clippers, Wizards and Knicks have had some of the worst management in all of basketball since the mid 90s. The Clippers refuse to spend money because Sterling is the worst owner in sports, the Knicks were ran into the ground by possibly the worst GM professional sports has ever seen and the Wizards have made a handful of horrible decisions since the 90s that have ran them into the ground. Of course throwing money at a problem isn't a good solution, but if you have a good GM and deep pockets, you can build a great franchise (Lakers, Celtics, Mavs), or if you have a great GM and a lot of luck you can build a great franchise (Spurs getting Duncan because of Robinson's injury, Jazz getting Malone and Stockton), but really those are the only two ways to win a championship and the number of option #1 teams winning championships for the last 30 years should show you which is easier to come by.
