I don't think this was about "pulling cards", I think he was just being honest about how his team played. I think he will be saying this more often now that his team isn't completely comprised of vets. The young guys need honest criticism to know how Pop expects them to play going forward, don't think it was some kind of ploy to try and turn the team around.
That said, Pop has no one to blame but himself for this team being so limp ed. Bonner and Jefferson seeing major minutes will give ED to just about any team...his rotation, his soft beef injection.
