Dominik Hasek. 28 before he became a true #1 but when he did he became one of the best goalies ever.
He played in Czechoslovakia and internationally in the 1980s, which should be taken into consideration.
How old is he here? Looks like about 55...Can I say, Connie Madigan? Oldest NHL rookie at age 37 when he broke in with the Blues in 1972.
Also, he played the legendary hockey goon Ross "Mad Dog" Madison in Slap Shot.
No way.
Guy was a juniors superstar who struggled his first couple of seasons because the coach tried to convert him into a center.
Franzen. Drafted at 24 yrs of age, makes the Red Wings at 26 as a bottom line checker, blossoms at the end and postseason of his 28 yr old season and then becomes a top line scoring winger during his 29 yr old season and beyond until injuries mounted.
Maybe Adam Oates? His draft year would have been 1981 (very nearly 1980), which puts him at almost the same age as Glenn Anderson and Denis Savard, yet those guys were having their last big seasons when Oates was having his first big one. Oates wasn't an NHL regular until he was 24, yet put up 1420 points.
Ray Whitney? Drafted in 1991, his first productive season was six or seven years later when he was 25. His four highest-scoring seasons are all past his 30th birthday.
From an older undrafted college kid who was at best an average 2nd line center behind Yzerman.
To one of the best playmakers the game has ever seen.
