Yeah for the other questions I don't know when message boards really became a big thing for fans to flock to, as these were the early days of the internet. I got onto one called Fanhome which used the same format currently on HF in '99, and knew of hockeysfuture.com at the time but the format was a lot shittier until they made the change to the current look in 2002. So in the summer of '97 I feel like it was a lot more face-to-face discussion at school/work/bar/etc, or was for me at least.
And in terms of the Messier signing it went from huge hype in the summer but quickly turned to anger and scorn that season. I know Messier was old but he was just coming off a great season in New York and we were supposed to be getting a 40 goal, PPG+, gritty ass kicking leader, which is why the team gave him a 3 year $21M+ deal. What we got was an arrogant 60 point floater that was so far up his own ass he tore the room apart making everyone worse that season.
One thing that's always bugged me talking about it years later is people supporting Messier's time here saying 'the Canucks were bad anyways'. This wasn't the '94 Canucks team anymore but they were still only one season out of the playoffs, and had a lot of good pieces in place but a big gaping hole down the middle. Like had we gotten Gretzky in '97, we probably make the playoffs in '97 and '98. The team was essentially:
Gelinas - *** - Mogilny
Naslund - Linden/Sillinger - Bure
Brashear - Sillinger/Linden - Noonan
Odjick - Scatchard - Walker
Lumme - Ohlund
Hedican - Aucoin
Babych - Murzin
Irbe
McLean
Plug in a legit top line center like Messier was supposed to be, or at least a good center with enough $$$ left over to also fix the #2C, and decent chance you're back in the playoffs.
