I am worried about the NHL 6 (the 6 current and former NBA owners that also owned a hockey team during the NHL lockout). They took a hardline stance against their players and lost a season. It resulted in, arguably, the most favorable collective bargaining agreement for owners in all of sports. I realize that three of those 6 owners either have or are in the process of selling their teams, but their fellow owners may well listen to them.
The biggest difference between the NBA and NFL lockouts is that some NBA teams are actually losing money and would lose less if they shut down for a year. That is not the case for the NFL. Nearly every knowledgeable NBA writer believes that a 50 game regular season is a best case scenario.
Another more subtle issue is the struggle for power. After last summer's debacle of a free agency, many owners feel that players have too much power. Many owners had their considerable pride hurt by the actions of LeBron, Wade, etc. That did not like having to kowtow to the top free agents, especially when it seems that LeBron, Wade and Bosh had already decided to play together in Miami. It may seem petty, but I can see the owners taking a hardline stance to "show the players who's boss."
