The first round of the NHL's Stanley Cup Playoffs came to a close on Sunday night. The first few weeks brought plenty of drama -- some of the expected variety and some quite surprising -- and there's undoubtedly more in store moving forward.
But with a few days to go before round number two kicks off, let's take a look at some of the things we learned over the past few weeks.

You can still have a great first round without any Game 7s
You might think that an opening-round without a single do-or-die Game 7 would be a disappointment, but that wasn't the case.
Sure, a seven-game series would have been nice, but the first round also set a single round record with 18 overtime games.
Also, 28 of the 42 games (66.7%) in round one were decided by a single goal, which ties an opening round record for highest percentage of games decided by a one-goal margin.
There were no Game 7s, but still plenty of drama.

The Maple Leafs are legit
Going into the playoffs, the Maple Leafs were a nice story. They went from the league's worst team to a playoff squad in one year thanks to a crop of talented young rookies that they'll build around for years to come.
But sneaking into the postseason wasn't good enough for the Leafs. Staring down an intimidating opening-round matchup against the Presidents' Trophy-winning Capitals, Toronto brought it. Hard.
They were fearless and they battled the Caps valiantly, taking them to six games before being eliminated. All six games were decided by a single goal, with five going to overtime to find a winner.
They may still be a bit away from being a true contender, but they made a lot of noise this year. They might be closer than we expected.

Changes are coming for the Blackhawks
The Blackhawks have been the NHL's golden franchise over much of the past decade, with incredible sustained success and three Stanley Cup championships to show for it.
But they were swept in the first round by the Predators this year, and in rather embarrassing fashion. They may have finished as the West's top team during the regular season, but GM Stan Bowman indicated that changes are coming to ensure that Chicago stays competitive.
The jury is still out on what that means exactly, but it's certainly not a comfortable time for anyone in that organization.

Marc Bergevin is on the hot seat
It seemed like not too long ago that Canadiens GM Marc Bergevin was somewhat of a hero in Montreal. He put together some very competitive teams and they looked to be in decent position to make a run at the Cup.
But then he traded P.K. Subban and that's when the second-guessing began.
After a first-round exit at the hands of the Rangers this year, the pressure is on. And it should be.
The Candiens' flaws were apparent for a while. They needed offensive help at the trade deadline, but Bergevin didn't get it.
Instead, he opted to add toughness and defense, hoping that the in-house offense would get improve on its own. It didn't.
Now it's on Bergevin to get the team back on track and in a hurry. He'll likely want to start with extending Carey Price's contract.

Bruce Boudreau's playoff demons are still present
Bruce Boudreau is a great coach and he was a big reason the Wild finished as the second-best team in the Western Conference during his first year in Minnesota.
But that impressive regular season under Boudreau was followed by a disappointing playoff showing -- again.
Despite eight division titles in his 11 seasons as a head coach, Boudreau is 42-43 lifetime in playoffs and has escaped the first two rounds just once. This is the fifth time he's been bounced in the opening-round.
If there's a silver lining, it's that Boudreau didn't have to come up short in another Game 7. He's still 1-8 in those. Hooray!
Goaltending, goaltending, goaltending
This is not news, but good goaltending is crucial in the playoffs.
Plenty of teams got it in the first round. Jake Allen silenced doubters with an incredible first round for St. Louis (.956 S%, 1.47 GAA), Henrik Lundqvist was huge for the Rangers (.947, 1.70), and Pekka Rinne stymied the Blackhawks (.976, 0.70).
Marc-Andre Fleury came up huge for the Penguins when Matt Murray suffered an unfortunate injury just prior to the start of their series. Cam Talbot, John Gibson, Braden Holtby, and Craig Anderson also came up big in their series wins.
But even most of the losing goalies had strong performances. Sergei Bobrovsky, Brian Elliot and Corey Crawford are probably the only netminders that aren't feeling so great about their first-round showings.
Pittsburgh thriving, not just surviving
Many anticipated the Penguins-Blue Jackets matchup in round one to be one of the more intense and competitive series, but it didn't work out that way.
The Penguins made quick work of Columbus and dumped them in five games, even as they played without a Norris-caliber defenseman in Kris Letang and their starting goalie in Matt Murray.
They looked great and, thus, the reigning champs are favored to repeat heading into the second round. That certainly won't be easy, as they're awaiting the loaded Capitals next.

Erik Karlsson is a monster
It's no shock that the leading Norris candidate played well in round one against the Bruins, but he did so with two hairline fractures in his foot.
Despite the injury, Karlsson was still the best player on the ice in the series and averaged 30 minutes of ice time per game.
He had six points in six games and drove possession for Ottawa, making them a completely different team while he was on the ice.
Looking at his consistent impact with the Senators, it's hard to argue against him being the defenseman in hockey right now.

Oilers fans were ready
After being out of the playoffs for a decade, the Oilers are heading to the second round with Connor McDavid at the helm.
They didn't have the most impressive first round in terms of performance, but Oilers faithful brought an absolutely electric atmosphere in Edmonton as they tried to amplify home ice advantage. It was a lot of fun to watch.
Fans seem to be embracing the "Orange Crush" theme, as Rogers Place was a sea of orange jerseys during all three opening-round home games.
The energy was great, but the bathroom lines were not.

Tides turning out West
If you blinked you may have missed it, but the Ducks swept the Flames in round one. They looked impressive and are poised to make a deep run, as they'll be a tough matchup for the Oilers next.
If nothing else, the Ducks can pride themselves on winning the Battle of California this season.
The reigning Western Conference champs in San Jose were very banged up in the first round -- Joe Thornton played on a torn ACL and MCL, Tomas Hertl had a broken foot, Patrick Marleau had a broken finger, and Logan Couture's mouth was a disaster worthy of relief from the Red Cross -- and sent home disappointingly early.
Meanwhile, the once-mighty Kings were busy firing their general manager and coach as they look to figure out where it all went wrong.

Henrik Lundqvist still needs thoughts & prayers
The Rangers are heading to the second round after taking the Canadiens down in six games. Henrik Lundqvist is a big reason why, and it was encouraging to see him return to elite postseason form after a shaky regular season.
However, we've seen this movie before, and it doesn't typically end well for Hank.
The Rangers' defense is still a liability and it was exposed a few times by pretty lackluster Canadiens offense. It's hard to envision Lundqvist's play making up for that over the course of an entire postseason, especially as the competition gets tougher.
New York should still be in good position to take a second round matchup against the Senators, but another bumpy ride seems inevitable as the Rangers move forward. Hank better strap in.

Charlie McAvoy is the real deal
The Bruins got bumped in the first round by Ottawa, but there's a few reasons Boston fans shouldn't be too distraught.
A depleted lineup -- especially on defense -- did the Bruins in, but it also allowed for an early look at Charlie McAvoy, the 19-year-old former first-round pick who left Boston Unversity to sign with the team just prior to the playoffs.
The Bruins had to burn the first year of his entry-level contract to get him into the postseason lineup, but they have to be impressed with what they saw.
He showed flashes of excellence while moving the puck and facilitating offense, as well as excellent poise and composure on a high-pressure stage.
He wasn't perfect -- he showed a little hesitation to shoot the puck and occasionally looked rough in his own end -- but that's to be expected.
The learning curve for young, incoming defensemen is tougher, but McAvoy showed that he has the potential to be a leader on Boston's blue line corps for years to come.
