I'll tell you what. I can see some type of player tampering rule being extended to players in the next CBA if this type of stuff continues. Players meeting to discuss getting together while still under contract with other teams. Players marketing companies talking to player telling them to request trades. Player making toasts in saying they will be getting together with other players in certain cities to play together while they are all under contract elsewhere.
This could get messy with the new CBA.
This is the only part I see as addressable. You can't really stop workers from talking with each other about where they'd like to work when their contracts are up.
I'd love to see stiffer restrictions on marketing influence but good luck: power hierarchy goes Marketing > owners > players.
I'd also like to see taxes equaled out in the next CBA: all players pay the same rate on their contracts to the league and the league foots the bill for all federal and state taxes; as it stands, florida teams have an automatic 10% more cap space than other teams, in effect!
And by the way, Anthony hasn't demanded a trade, and Pierce, CP3, Anthony, KG and even Kobe haven't missed any contractual obligations when they asked for or hinted at wanting trades. So I'd say their honoring their contracts just as much as, say, NFL owners who can sign and cut players on a whim and not for failing to live up to specific contractual markers.
