"We don't publicize discipline for officials. We don't think that will be appropriate," Silver said Friday in an interview with ESPN's Sage Steele on SportsCenter. "But their assignments are affected by the quality of their calls, whether or not they progress into the playoffs and then round by round is impacted by the accuracy of their calls and their demeanor on the floor. So there is a system for overseeing and making those judgements about officials. But more to your earlier point about getting the calls right, that's again not a new issue."

"I don't want to suggest there's a magic bullet here," Silver said. "I don't think it's just about incentivizing players to play more, that the teams are as much a part of the load management as the players are, because again, I think there's been a societal shift. Everything's about winning a championship these days and it's less, I think in all sports, about how you perform day in and day out. And so it's a cultural issue as well.

"There are a few things we're addressing in collective bargaining, for example, I think we ensure that some of our awards require a minimum number of games be played, that we're celebrating not just average number of points, but total number of points, that the culture is guys being out on the floor as much as they can."
