PRE-QUESTION NOTE: Today is a Theme Day. Theme days can be overt, or they can be subtle and connected, in such a way that figuring out the theme may help you answer the questions. Good luck.

Though the Bulls, Packers, Lakers, Maple Leafs, and A’s have come close, the New York Islanders, Montreal Canadiens, Boston Celtics, and New York Yankees are the only teams in the major North American sports leagues to accomplish what feat (post-1915)? We’ll be open-minded when grading your answer, but be aware that as far as the theme day goes, slang is your friend.

In the image below listing the top six players in NHL career assists-per-game average, which 2003 Hart Memorial Trophy winner, two-time Stanley Cup winner with the Colorado Avalanche, and two-time Olympic gold medalist has had his name redacted?

When describing the “only regret” of his career in a 2015 autobiography, which athlete wrote the following:
 

“Some days I feel more people remember me as the angry young man who pushed down a defenseless old man than as the [player] who wound up in the Hall of Fame.”

The all-time top goalscorer from Gabon (and the top all-time non-German scorer for Borussia Dortmund) has a hyphenated first name, and the player who is currently 53rd on the official NFL career sack list (and no. 1, we assume, among victims of fireworks mishaps) has a hyphenated last name. What name do the players share in the hyphenated parts of their names?

Since 1900, only one major champion in professional golf history has a father who also won a major (not counting senior tours). Name the father, and note that this is absolutely a sneaky trick question.
