BOSTON (AP) -- NBA Commissioner Adam Silver says he would consider shortening the regular season, but only if the league could develop something meaningful to do to replace the games - and revenue - they would be giving up.Speaking at the MIT Sloan Sports Analytics Conference on Friday, Silver raised the idea of replacing the All-Star Game with a midseason or preseason tournament in which teams would compete for a separate championship, like they do in European soccer. Or groups of teams could compete in mini-tournaments in Asia or Europe.The problem, Silver said, is how to make these other events meaningful."The All-Star Game didn't work," he said, calling it "an afterthought" of the weekend despite changes like tinkering with the rosters through a player draft that was made public for the first time. "I get it. We put an earring on a pig."The league is unlikely to make any changes - at least not any time soon - if only because a 70-game schedule like the one Silver discussed would require each team to give up six home games. Although players and coaches would love to see a shorter season, none is excited about taking a 20 percent pay cut.
