This is Jean Ratelle.
Ratelle entered the league as a 20 year old and put up only 2 goals.
Then as a 21 year old he put up 4 goals
As a 22 year old he scored 11 goals
Then he had a absolutely terrible season at 23 with 0 goals
Ratelle somehow got another shot in the NHL and was able to put up 14 goals as a 24 year old
And then Ratelle finally actually had a semi good NHL season as a 25 year old with 21 goals.
But it wouldn't last as he fell to just scoring 6 goals as a 26 year old.
So after 7 years in the league Ratelle had scored only 58 goals and it was looking more and more like he was heading over to the AHL the following season.
But Ratelle stopped fooling around and did some serious work in the off season on his skating and slap shot.
And during the next 13 seasons in the NHL he scored anywere between 25 and 46 goals every season. And when it was all said and done Ratelle got 491 career goals and made the Hall of fame!
