Bobby Hull is the classic case.
He has stated that at 22 he expected to win it again and never did.
It was really cool that Wirtz Jr classed up and Hull was back in the Black Hawk fold when the Hawks won it last year.
Bill Wirtz himself was too much of a grouch to ever let that happen.
I'll throw another name out there. Patrick Flatley. No, he didn't have a "great" career by any means unlike his co-rookie in 1984 Lafontaine, but he never got to the final after 1984.
How about Ron Hextall? Had a season for the ages in 1987 one game away from the Cup. Yes I know he did play in the 1997 final but it was a shared duty with Snow, in fact Hextall only played in 8 games that spring. He's close enough to a HHOF career.
This may sound weird, but Paul Henderson made the final twice in his first three years. Never again. Plus he never did anything else worth talking about afterwards
In his sophomore year Roger Crozier took the Red Wings to the final in 1966. I know he played sparingly with the Sabres in 1975 but wasn't their main goalie.
Pete Peeters was a rookie with Philly in 1980. Never made the final again. Is a shade below the HHOF, so I guess he isn't "great" either
