So the next time a player talks even a little trash to Melo everyone will be like, "Oh, see! Melo is the one who takes crap all time! He never starts anything! Not even a post-game altercation outside the opposing team's bus while being protected by a bunch of cops so he doesn't get his tail kicked. MELO FOR MVP!"
Well that's the thing...
They can't really show anyone what's being said unless the players have that as a contractual obligation under the MSG network.
I know for a fact that players/coaches can choose whether or not to be recorded by networks like TNT/ESPN etc and paper is actually signed so the networks can use those recordings. The Knicks aren't on a different planet as far as the law is concerned. As much as melo would like them to be.
Not to mention being an audio engineer by trade; I know how difficult it is to get a clear recording of moving people in a loud crowded environment with a shotgun microphone. You point the shotgun an inch too far to the left, and you're recording people in the third row, not melo.
Aside to the fact, all this hubbub from one incident has shown that Kevin really got under melo's and the team's skin. Now teams know it works, they will go hammer and tongs at the Knicks.
