At the start of '80, they should indeed have gone after a goalie.
Richard Brodeur was available for DARN, DARN cheap.
(the trade was Brodeur, NYI 5th for VAN 5th).
BTW, how did Brodeur play only TWO games in 79-80?
Hindsight is 20/20. At the start of the 1980 season I don't think the Habs brass would've seen the need. They had just traded for Denis Herron the previous. Herron had had a superb season the previous year, marred by his game 7 gaffe. Richard Sevigny was being groomed in the minors. People forget Sevigny was pretty well regarded coming out of juniors. He'd played on Canada's squad in the World Juniors as an 18 yr. old and had won a Presidents Trophy with the Sherbrooke Castors the following year. There was also Mark Holden, an All-American in '79-80 from Brown in the mix and they had just drafted Rick Wamsley in the 3rd rd. of the '79 draft. Plus Larocque was still in the fold. Unfortunately for the Canadiens none of these goalies proved to be of championship mettle come the playoffs.
One also has to ask if the Islanders would've been willing to trade an asset like Brodeur to the Habs. Yes, the Canucks got him for cheep, but I doubt Bill Torrey was looking to make the Canadiens get better in the fall of '80.
I think you would be very hard-pressed to find Canadiens fans that would back this up.
He didn't make any disastrous trades that in any way hurt the franchises, he won a Cup, and under his watch the team drafted stars like Guy Carbonneau who went on to captain the Canadiens to a Stanley Cup, Mats Naslund, who was integral to the '86 title and Hall of Famer Chris Chelios.
The only real blunder on his watch was the Wickenheiser over Savard draft pick, though I suspect that is on the scouting department, not Grundman.
It's silly to compare him to a total dud like JFJ.
Now Rejean Houle, there's a GM that riles up fans and has a laundry list of errors to his name.
Ron Caron made that call, the same man who convinced Pollock to pass on Bossy. Because of Caron the Habs passed on the two best Montreal players available during that time.
I think your assessment of Grundman is more or less correct, to a point. His low-balling of Lemaire in contract talks led to the Habs losing their #1 center. Otherwise I would say Grundman's greatest failings were internal management issues that affected the play on the ice. He dithered over a replacement for Bowman, not deciding on Bernie Geoffrion, a man who had already walked away from two previous coaching gigs because of ulcers, until Labour Day weekend, just weeks before the season was to begin. There would be issues also around Bernie's son Danny's attitude and playing time that affected the locker room.
The decision to draft Wickenheiser over Savard caused a rift between Caron and coach Claude Ruel, who had desperately wanted Savard. Ruel effectively benched Wickenheiser throughout his rookie year out of spite.
Grundman wasn't awful, but he just wasn't a strong leader either.
Agree wholeheartedly with Panther and Ferris about Bowman. He was a disaster in Buffalo and I don't think he would've been any better in Montreal. And people fail to understand that the Habs offered Bowman a chance to be GM, it just wasn't on the total control terms that he wanted and got in Buffalo.
