Brett's career began in the 1982-83 season with the Penticton Knights of the BCJHL where in his first season he scored 48 goals in 50 games for a total of 104 points overall. That was his worst year! In the next season he set a new league record for scoring(105 goals) and points(188). In 1984 Hull was selected by Calgary as their sixth draft pick and 117th overall, and he spent the next 2 years at the University of Minnesota-Duluth where he notched over a point per game.

In the 1986-87 Hull was called up for 5 games with Calgary but was then sent to Moncton of the AHL where he was selected to the first All Star Team and won the Dudley "Red" Garrett Memorial Trophy as the Top Rookie. The following season Brett was called up and played 52 games, tallying 26 goals and 24 assists before he was traded to St. Louis on March 7, 1988 along with Steve Bozek for Rob Ramage and Rick Wamsley. As with most teams, this would be one trade that Calgary would regret.

Hull wasted little time in establishing himself as a force to be dealt with. In his first full season with the Blues(1988-89) he scored 41 goals and 43 assists in 78 games. The following season was the first of three consecutive seasons that Hull led the league in scoring with 72, 86, and 70 goals. His 86 goal season in 1990-91 put him into a select group with Wayne Gretzky and Mario Lemieux as who have scored more than 80 goals in a single season. Hull's performance that year ranks him third in the Most Goals in a Season behind Gretzky's 92 and 87. Over the next 2 seasons Brett tallied 54 and 57 goals to pass Bernie Federko(352 goals) as the Blues' all time leading goal scorer. Hull would eventually up that total to 527 goals over the next 4 seasons. Management disputes and poor production made a change necessary and on July 3, 1998 Hull signed as a free agent with the Dallas Stars.

Hull scored the Stanley Cup Final winning goal of 14:51 of the third period ending the second longest Stanley Cup Finals game in history. Above and beyond his "trophy" awards Brett holds the St Louis Blues team records for the most goals(527), the Most Goals in a Season(86) the Most Points in a Season(131) and the Most Points by a Right Wing in a Season(131). Brett currently(end of 1999 season) sits at 12th on the All Time Goal Scoring Leader list with 586 goals and is 3rd on the Active All Time Scoring list only 24 goals out of first place, held by Mark Messier. Hull however has attained his mark in 861 games and Messier has done it in 1413 games. Will Brett Hull top his father's performance? The answer is yes. At the end of the 1999 season he was only 24 goals behind Bobby's 610 and 125 points behind Bobby's 1170. Hull's rocket like shot and quick release are feared by almost every NHL goalie. When you see Brett at the edge of the face off circle in the "ready" position, you know that it won't be long before he gets the pass and one times it into the net.
