Is it necessary for a team to exceed the hard cap to stay competitive in the NBA similar to the MLB (Red Sox, Yankees, etc)?
The simple answer is No. If you break the NBA down into three tiers of payroll, here are the results.
Highest Payrolls = .471 win percentage
Middle Payrolls = .577 win percentage
Lowest Payrolls = .452 win percentage
Using the same tiered system to analyze teams only in the WESTERN CONFERENCE, you get the following numbers:
Highest Payrolls = .529 win percentage
Middle Payrolls = .627 win percentage
Lowest Payrolls = .424 win percentage
Looking solely at statistics, one could create a reasonable argument to state that teams should not be extreme penny-pinchers, although they shouldn't reach the other extreme by opening their pockets for anyone who has ever had a good season.
Among the highest and lowest paying teams in the NBA, you'll find:
Miami = $150M in 2007-08 including luxury taxes paid
New York = $135M in 2007-08 including luxury taxes paid
Denver = $130M in 2007-08 including luxury taxes paid
LA Clippers = $57M in 2007-08
Milwaukee = $59M in 2007-08
Memphis = $48M in 2007-08
Philadelphia = $45M in 2007-08
While teams want to avoid either extreme, there is no exact recipe for success. Many people ask "can a team in a small market like Utah afford to pay high taxes in the NBA and stay afloat"? Given the right scenario, the answer is YES.
The San Antonio Spurs ranked 6th in the NBA last season in payroll which reached approximately $110M including luxury taxes. San Antonio is really a smaller market that Utah, but the Spurs have gained a national following by staying competitive for multiple seasons and winning multiple NBA championships.
Our blogger team has put together a spreadsheet that shows the Utah Jazz salaries for the coming years.
The yellow cells mark the quality players eligible for signing an extension after next season with their expected salaries. Don't forget, a team can't operate with only 6 players however, and a portion of salaries must be kept aside for bench players to fill out a roster. In addition to those listed, the Jazz have zero first round draft picks in 2009, two first round draft picks in 2010 (including one from the NY Knicks), and 1 first round draft pick in subsequent years following.
I don't know how to post the pictures/statistics, but they are on the website.
