I really doubt this happens, and if it continues to be part of the new CBA negotiations, you'll most definitely see a lockout. A hard cap will eventually restrict where free agents choose to go. If all contenders are at the cap, or a hair below it, big-name players will literally be forced to go to a struggling team, or in many cases, a small-market team. And in restricting team availability, it will force salary cuts. Someone like John Wall may be a deserving max player, but the only teams that could offer the max are the Bucks, Cavaliers, Pistons and Pacers...and assuming they are all struggling, and they aren't Los Angeles, Miami, or New York (where all big-name players want to go because of the market), Wall will have to look to a team like Denver, who may have a little less money to offer, is a better team, but not exactly cream of the crop (yes, Melo has left). So, really, a free agent really won't be free anymore. Also, you create a problem come draft time, if a team is maxed out and has a top pick. That's $3-4 million they will need to shed off of their roster just to sign their top pick, which could mean some deserving player ends up out of a job because his team had to waive him. Most all contract lengths will be shorter (much, much shorter) for guys like Oden, Yao and Bynum, who have been suffering from injuries over the last three seasons, because teams know they will NEVER be able to get out of those contracts once they write them up. How many times will you see a team offer expiring contracts in deals for non-superstar players? It would be much easier to pick up a superstar through free agency, with the hard cap, so teams will more than likely keep their expiring contracts, even of those players who are barely logging minutes. Could lead to more teams tanking seasons, keeping useless players on their rosters just to have an extra $18 million for the following season. You drop the luxury tax, and suddenly, the NBA doesn't make money off of it. I could go on and on.
