Football offers first-round byes to the top teams in the playoffs. Baseball offers a shorter series in the first round.
Basketball, while having a similar format, does not have the blood-spilling, bone-crushing effect of Ice hockey.
Hockey is all out war in the playoffs. A team isn't dead until that final buzzer goes off in your fourth win of a series, just ask the Boston Bruins about that.
All sports offer a higher tempo in their postseasons, but the NHL's is a crucible of blood, guts and honor over almost two whole months. That's like half a season of football. This past Stanley Cup winner had to play 27 games just to hoist the trophy! That's like playing an NFL postseason 10 times.
The games are a day apart, except for travel nights throughout the tournament. Even basketball doesn't play that many games that close together.
Even though you get hit harder in football, the players are ground up more at the end of Lord Stanley's tournament.
