Does Money Buy Championships?

As we all know in the NBA, Championship teams differ from the rest of the league. They tend to emphasize teamwork, cohesiveness, and feature some of the best talents in the NBA, however are they also the most expensive to build?

The chart belows shows the most recent championship teams and how there team salaries compared with the rest of the league.

Year	Team	Salary	Salary Rank
2008-2009	LAL	$80,745,793	5th
2007-2008	BOS	$73,812,248	7th
2006-2007	SA	$65,645,095	6th
2005-2006	MIA	$59,651,468	10th
2004-2005	SA	$47,404,123	21st
2003-2004	DET	$52,942,639	14th
2002-2003	SA	$52,817,688	17th
2001-2002	LAL	$52,985,249	13th

Unfortunately I don't have salary data ( at least not without painstaking manual calculations) past 2001-2002 season (if anyone got resources for that I would to know).

By looking at this 8 year span, the trend seems to tilting towards teams with higher salaries winning championships. Also, this trend doesn't look to stop anytime soon as top contending teams LAL, DAL, BOS, ORL are going to have some of the highest team salaries in the league for the next few years.

Is it time we do something about it? Will the NBA spending spree prevent lower cap teams from competing?
