Hossa scored 525 goals, ranking 35th in NHL history and 29th in the expansion era, in 1,309 games for the Ottawa Senators, Atlanta Thrashers, Pittsburgh Penguins, Detroit Red Wings and Blackhawks. He was third among active players behind Alex Ovechkin (607) and Patrick Marleau (535).
Given the changes in scoring levels over the years, it's important to make adjustments when comparing players across eras. Hossa scored his first NHL goal Dec. 9, 1998, when goal-scoring rates had begun dropping from more than three per game throughout the 1970s, 1980s and early 1990s to about 2.7 per game in the 2000s.
As an example of the impact this can have, compare Hossa to Michel Goulet, who ranks 29th in NHL history with 548 goals in 1,089 games. In the decade beginning Jan. 1, 2000, Hossa scored 317 goals, third most behind Jarome Iginla (360) and Ilya Kovalchuk (320). In the decade beginning Jan. 1, 1980, Goulet ranked third, but with 441 goals, behind Wayne Gretzky (637) and Jari Kurri (460). Hossa undoubtedly would have scored more if he debuted in the NHL 20 years earlier.
The most common way to compare players across eras is to divide each player's total goals by the average player's goals-per-game average that season, then multiply that number by the modern standard of 0.15 goals per game.
When making that adjustment for every NHL player since the 1967 expansion, Hossa's modern equivalent of 531 goals ranks 18th.
