Here's what you need to know today from the world of sports:

The upsets haven't really materialized

Before the top North American sports leagues returned from their long, pandemic-induced stops briefly, the standard knowledge was that these video games would be a free-for-all. After being off for months, there was no telling who 'd reveal up ready to play and who may be doing not have an edge -- or just merely out of shape. Plus, with everyone thrust into unusual, fanless places -- and NHL and NBA video games being played at neutral sites -- there was a sense that the playing field had been levelled to some degree. Lots of people expected a ton of upsets.

That's not the method it's played out. The NHL, NBA and Major League Baseball restarts are looking quite chalky up until now. Here's a take a look at how the favourites are remaining on top in each league:

NBA

Because its star players can influence the result of video games more than those in other sports, basketball has never lent itself to upsets. That hasn't really altered up until now in the Disney World bubble. Three of the four opening-round series in the Eastern Conference resulted in a four-game sweep by the wagering favourite. The other is most likely to end in five after top-seeded Milwaukee rebounded from a Game 1 misstep with 3 straight convincing wins over Orlando.

Underdogs are faring better in the West. Considering it's the much deeper conference, have we actually seen anything all that shocking? Sure, 6th-seeded Utah is up 3-1 on 3rd-seeded Denver, however those teams ended up two video games apart in the standings and many people saw the series as a tossup. The 4 vs. 5 matchup between Houston and Oklahoma City, who had similar regular-season records, is tied 2-2. The top-seeded Lakers are up 3-1 on Portland. The only real surprise is No. 7 Dallas providing the 2nd-seeded Clippers all they can manage. But still, that match is tied 2-2 and L.A. is a Luka Doncic buzzer-beating three away from being up 3-1. The Clippers are favoured by 7 1/2 points tonight, so the Mavs have a lot more work to do if they're to manage the series upset.

MLB

With the regular season cut from a 162-game marathon to a 60-game sprint, and several rosters currently annihilated by positive coronavirus test results, baseball seemed to be producing the perfect environment for wackiness. It's the reverse.

None of the six division leaders are truly a surprise. In the National League, the West-leading Dodgers have the very best record in baseball, simply as everybody forecasted, while the Central-leading Cubs and East-topping Atlanta were either co-favourites or favourites to be in this area heading into the season. In the American League, Minnesota leads the Central, as anticipated. The majority of individuals had the Yankees winning the East, but they're just a half video game behind Tampa Bay, which was a playoff group last year and a fairly popular pre-season pick to take the department themselves. Oakland is a moderate surprise atop the West, however they had the fourth-best record in the AL last year and pre-season favourite Houston is still doing OK in second location.

NHL

Ha! This is where the premise falls apart, right? In the playoff qualifying round, the No. 12 seed in each conference beat the No. 5. But hold on. While few individuals forecasted Montreal would secure Pittsburgh, plenty provided Chicago a good shot versus a deeply problematic Edmonton team. The other upsets in that round were quite moderate: Columbus over Toronto in an 8 vs. 9 matchup, and Arizona over Nashville in a 6 vs. 11 snoozefest between 2 lowly concerned teams that completed four points apart in the standings.

And do not forget, those were all best-of-five series, which are friendlier for upsets. When the format changed to the standard best-of-seven for the next round, just 2 of the 8 underdogs won: the 6th-seeded Islanders bounced 3rd-seeded Washington, and Vancouver took out defending-champion St. Louis in a 4 vs. 5 match.

This is the NHL, where upsets are the norm and not much appears to separate the top teams from the mediocre ones anymore. Take a look at last year's playoffs: Tampa Bay had one of the best regular seasons of perpetuity and then got swept by 8th-seeded Columbus in round 1. The St. Louis Blues went from dead last in the total standings to Stanley Cup champs in 5 months.

It's also worth keeping in mind that the consensus two finest groups in each conference -- Boston and Tampa Bay in the East, Vegas and Colorado in the West -- all won their first-round series in a breezy 5 video games. Colorado seems in difficulty now after dropping 2-0 to Dallas, but there's still a ways to enter that series.

So what's going on here?

Why aren't we seeing the amount of upsets many individuals anticipated? Here's my theory: rather than levelling the playing field, the NHL's and NBA's bubbles and MLB's empty house arenas have produced a lab-like environment that eliminates numerous of the variables that assist create randomness. There are no raucous crowds to sway the refs/umps into making calls that favour the house team. No basketball or hockey gamers are showing up to video games jet tired or lagged from a long flight. Without loved ones around, it's simpler to turn in early for an excellent night's rest. Under these more controlled conditions, there's less to go wrong for the favourites. Skill and ability triumph. Simply like we're seeing.

The league's 9 clubs (consisting of Orlando) have been divided into three local "pods" to lessen travel, and each group will play the other two in its pod two times.
