If Perk is miffed, it's probably because he keeps reading quotes from Danny that his health was a major issue, that Shaq was the better player, and that Perk wanted too much money by rejecting the lowball, CBA-mandated extension offer.
I'm sure Perk has a different view of the reality of each of those situations, and if he talks about Danny trying to look good by covering up the truth, my guess is that's what he's talking about.
I wish Danny had just said, "Listen, I made the trade that I thought was best for the team. I was a big Perk fan, and I wish him the best." Instead, we've gotten reason after reason about why the trade had to be made (with some of those reasons evolving over time.) Danny has seemed to be in full-on spin mode, and I've found it a bit distasteful. I'm sure that Perk feels the same way, since his former boss is basically taking shots at him on his way out the door.
