1. I don't think there's any set protocol to follow. And in this case, I'd forget about any unwritten rules. People can say what they want, although I kinda wish Peter didn't say anything in this case. Really, it sounded like he had no idea what he was talking about... a Stanley Cup this year? I like his optimism, but we had no defensive depth from the beginning.
2. I think so. When the Avs drafted Matt Duchene, they had a young, yet strong forward corps in Stastny, Hejduk as the veteran, Duchene, Stewart, Wojtek Wolski, and Marek Svatos (although he flopped badly that year). With Sherman trading away Wolski and now Stewart, I can't help but wonder if Peter thinks his son's next. Sherman trading away good players like Stewart and Scott Hannan probably doesn't help Peter breathe any easier. If Peter does think Paul's next to go, though, I think he's being overly paranoid. But to your question, I think it's got everything to do with Paul.
3. Not at all. We would've been set back 2-3 years if we kept relying on Hunwick, Wilson, and even offensive-minded defensemen like Liles and Shattenkirk to help our goalies out. Even if the Avs lost this trade to St. Louis, which I personally think we did, albeit not by much at all, Erik Johnson is a good start for our defense.
4. I didn't know they had a relationship besides Peter being an alumnus. I guess the situation may get more tense, though. Hopefully that won't be the case.
5. Paul should be fine. He better be, anyway. I'm sure he had his thoughts about letting two pretty good players in Stewart and Shattenkirk go, but if he's kept them to himself, hopefully the media doesn't force Paul to talk now that Peter's made these comments.
