Maybe even death and taxes aren't certain anymore; science, medicine, global warming, politics throwing everything up in the air. And before that, the Lakers and 76ers met in the 1980, 1982 and 1983 National Basketball Association finals. "We don't go into any series saying we're only going to play four games, we can't approach a series like that, like, 'Yeah, we're going to play four.' You approach it with a mindset of, 'Of course we'd love to sweep them but you have to take that game by game'".

It has never happened in football's European Cup and, closer to home, has never happened in Super Rugby, unsurprisingly for a competition so young.

It will be James' 7th straight trip to the finals and 8th overall.

The coach just turned 47 years old two months ago.

Who isn't consumed with this? "That's all I can give you right now, because I'm happy and I don't want to be stressed".

"I have no discussion - Golden State, they've been the best team in our league for the last three years, and then they added an MVP".

"I think first of all I wear the number (23) because of Mike", he told reporters after finishing the game with 35 points to take his total to 5,995 points.

"I'll take LeBron James, absolutely", Laimbeer said to Etan Thomas on The Rematch podcast (h/t Marlowe Alter of the Detroit Free Press, via USA Today). The topic emerged again Thursday night as James led the Cavaliers back to The Finals and passed Jordan on the all-time playoff scoring list.

The NBA limits salaries for individual players, meaning an already-stacked Warriors team could only offer as much money for Kevin Durant as any other team that doesn't have a shot at winning a title. I was watching before tonight's game the game that they played in Golden State.

So with that behind them, what do the Cavs have to worry about?

And there will be reminders of the Halloween party that James threw for the Cavaliers last fall, with "3-1 Lead" - a nod to what the Warriors lost in last year's Finals - prominently displayed on the drum set.

In the National Hockey League, the Pittsburgh Penguins bested the Ottawa Senators 3-2 Thursday night in Game 7 of the Eastern Conference Finals to take the series.

As far as the Cavs and Warriors are concerned - and virtually everyone in Northeast Ohio knows this - Golden State won in six games in 2015, when Cleveland was without Kevin Love and lost Kyrie Irving in Game 1, and the Cavs triumphed past year when the Warriors' Draymond Green got suspended for Game 5 and Cleveland became the first team in National Basketball Association history to win a Finals series after being down 3-1. He will wait for more tests until the swelling goes down, he said. "But it doesn't mean anything going into the next series, and we have to understand that". They do something, we come back and do something. "It's a great thing". It's not the end of the world. There was nearly too much historical context to dissect, and so James did what his instincts told him to do. If that's 4-0, great.

Isaiah Thomas still is in wait-and-see mode with regards to his hip injury. But honestly, probably not.

It remains to be seen whether the addition of Durant will propel the Warriors to victory, or LeBron will secure a second-straight championship for his city. Enjoy the show. Realize you are seeing history.

In the 1980s, at the height of the rivalry between Larry Bird's Celtics and Magic Johnson's Lakers, the teams met three times in four seasons between 1983 and 1987.
