Some will argue that Debrusk made knee-to-knee contact with Kadri earlier in the game.
The Leafs downed the Bruins 4-1 in the Wednesday's opener at TD Garden before falling by the same score on Saturday.
"I thought it was clean", Cassidy said.
"Naz is a good player and an important guy on our team". Ours wasn't as good as it needed to be.
"It's a regroup opportunity for us, that's all there is".
"The difference was special teams". It was their first playoff berth since 2003-04, and they likely wouldn't have made it in a full 82-game season.
The Bruins are 1-1 against the spread and 0-0 on the road. The Leafs' fourth line of Moore, Frederik Gauthier and Tyler Ennis were effective all night with a couple of grinding shifts in the offensive zone.
Boston hit everything in sight, jumping out to 3-0 lead in the second period before Kadri scored midway through the third, about four minutes before his cross-check on DeBrusk.
But the Bruins quickly reminded the Leafs why they finished ahead of them in the Atlantic Division race when Leafs defenceman Jake Muzzin took a holding penalty late in the period.
Matthews put Toronto back in front just 12 seconds after David Backes was whistled for high-sticking on Kasperi Kapanen, taking a feed from Johnsson and burying his first beyond an outstretched Rask to send Scotiabank Arena into a frenzy at 10:12.
The amusing thing about that was that the on-ice part of his game wasn't even what anxious the Leafs most.
The Bruins are 5-2 in their last 7 meetings with the Maple Leafs and 15-5 in their last 20 games following a win while the home team is 6-2 in the last 8 meetings between these sides.
First of all, Thursday's 4-1 win already represents an improvement over previous matchups: in fact, its the first time the Leafs have won the first game of a playoff series since 2003 against the Philadelphia Flyers. He had a goal and an assist in the first two games of the postseason.
After that run-in in the first period, which landed both players with matching minor penalties, there was another incident in the middle frame.
Toronto Maple Leafs forward Nazem Kadri has officially been suspended for the remainder of the first round of the playoffs. However, since the suspension is for fewer than six games, he's ineligible to eventually take his case to a neutral arbitrator in an effort to get it reduced.
"You have to play real hard and look after yourself, but you can't cross the line", Toronto head coach Mike Babcock said on a conference call with reporters Sunday. "Ideally all those things are contagious". "You've got to stay with it and find your game".
The NHL's department of public safety tweeted it had offered Kadri an in-person hearing. He received a three-game suspension during last year's playoffs - against the Boston Bruins as well. He is an excellent third line center and is under a good contract.
Kadri laid the vicious cross-check after DeBrusk hit Leafs veteran Patrick Marleau into the curved glass at the end of the bench.
At the end of Game 2, the statistics reflected Boston's domination. "Game 3, he should drop the gloves with DeBrusk and go toe-to-toe at center ice, set the f-ing tone for the home crowd".
