Here are some things we learned on Day 28 of the Stanley Cup Playoffs:
Penguins are winners
The Penguins played again with the heart of a Stanley Cup champion in defeating the Capitals. After the Penguins let a 3-1 lead in the best-of-7 series slip away with losses in Games 5 and 6, they regrouped and played their best game of the 2017 Stanley Cup Playoffs. Fleury helped them withstand the Capitals' early push, and they gradually took over the game in the second and third periods. The Penguins are halfway to becoming the first Stanley Cup champion to repeat since the Detroit Red Wings, who won in 1997 and 1998. The Ottawa Senators are up next in the Eastern Conference Final.
Capitals are cursed
Well, maybe they're not cursed, but despite all their talent and regular-season success, they can't figure out how to get past the second round of the Stanley Cup Playoffs. They've won the Presidents' Trophy two seasons in a row and lost to the Penguins in the second round each time. This was the most complete team of the Alex Ovechkin era, which began in 2005-06, but they still couldn't get over the hump. With changes likely coming this summer, this might have been Ovechkin's last, best chance at winning the Stanley Cup.
Oilers aren't there -- yet
The Oilers got the start they wanted against the Ducks, with rookie Drake Caggiula scoring 3:31 into the game. Though Edmonton seemed to make the Ducks nervous for the duration of the first period, they couldn't grab control of the game, and from the second period on, could not stop the Ducks' attack. Edmonton may have a bright future, but on this night, the Oilers couldn't get over the hump.
Randy Carlyle made right moves
Ducks coach Randy Carlyle has been known as one of the game's best in-game tacticians, and he lived up to that reputation in Game 7. The Ducks needed to match the Oilers' physical presence, so in the second period, Carlyle put physical forward Nick Ritchie on the top line with Ryan Getzlaf and Corey Perry, and moved the more skilled but less physical Rickard Rakell to the third line. That's when the tide started to turn in the Ducks' favor.
