Apparently the league is looking into cases of tampering during free agency, which I'm sure there was plenty. I think the Suns and handful of other teams were the only teams that didn't make some sort of deal before free agency opened.
There is always some chatter but this year was insane. The second it hit 6pm EST all deals were announced, they weren't discussed or negotiated. Most of the current playoff teams seemed to make their moves prior to free agency opening though, at least Woj was reporting things that way. All the league should need to do is get Woj and Shams to testify on how they heard things prior to free agency opening and 90% of the league would have questions to answer. It doesn't seem that Silver is as hard on these things as Stern was. No one messed around when Stern was in charge because he was quick to drop the hammer.
