The PP started to click well in the last five games or so. I wonder if maybe Sacco ran it originally, and they let Army have a shot at it, and then it took off. Just a stab in the dark guess.
Like others have said, I can't be too critical since I don't know what he did, but even if he did well, I'm surprised they don't want to just go with a clean slate, and let Patrick bring in another guy he knows.
If the video coach rumor is true for Laperriere, I'm surprised Patrick would go with Army (who by all accounts he doesn't really know) over his former assistant in Quebec that he's really close with for the Avs assistant job. Kinda sounds like this was Sakic's and management's choice, since they're familiar with Army, and maybe because Army's familiar with the players.
