Ovechkin led the NHL with 49 last season, and in 2007-08 (65), 2008-09 (56), 2012-13 (32), 2013-14 (51), 2014-15 (53) and 2015-16 (50).
The No. 1 pick in the 2004 NHL Draft, Ovechkin (33 years and 201 days old) is the sixth player to lead the NHL in goals at age 33 or older, the first since Phil Esposito in 1974-75 (33 years, 45 days for the Boston Bruins). The other players to do so are Bill Cook in 1932-33 (36 years, 165 days for the New York Rangers), Gordie Howe in 1962-63 (34 years, 358 days for the Detroit Red Wings), Nels Stewart in 1936-37 (34 years, 82 days for the Bruins and New York Americans), and Maurice Richard in 1954-55 (33 years, 228 days for the Montreal Canadiens).
Ovechkin reached 50 goals for the eighth time in his 14-season NHL career when he scored No. 50 and No. 51 against the Tampa Bay Lightning on March 30. Wayne Gretzky (Edmonton Oilers, Los Angeles Kings) and Mike Bossy (New York Islanders) hold the record with nine 50-goal seasons.
"I've had a couple of chances in previous years to score 50 but I didn't," Ovechkin said. "You always want to do something special, obviously, but sometimes it's hard. I'm happy to get it done."
