I really get a feeling that PDA is behind all of these "sources".
Yes. I would tend to agree that Karl may have been asking to trade DMC for more of his type of players, i.e. Lawson and Faried, at the end of the season, when PDA was still here. Which I also believe that Vlade and Vivek promptly shot down.
Here is where the weasel PDA let's out the "rumor" of Karl is trying to trade DMC, to cause more spite between the Kings and DMC camp, knowing full well that Vlade would not allow that to happen. As Vlade has stated numerous times DMC is not going anywhere.
Karl gains nothing for letting out this "rumor", it will only cause him more problems with his franchise player, whom he know is not going anywhere.
Now, who benefits from re-starting this rumor???? Who else but the weasel PDA.
PDA knows Vlade will not trade DMC, despite any wishes (previous or current) of Karl's, but that will not stop his bitter a** from spreading these rumors to get petty revenge and try to get DMC to the Nuggets. More discourse for DMC, the better for PDA and the Nuggets to try and pry him away.
Vivek and Vlade really needs to file for an investigation and tampering with the NBA against PDA and the Nuggets (and Mike Malone too, if he is in on it).
