Context matters, they were going up against Tatar-/Evans- Danault - Gallagher . That line put up 3 points against Toronto. Against The Jets after Tatar benched and Evans hurt in game one it was Evans/Lehkonen- Danault-Gallagher and they put up 8 points against jets. The lehkonen-Danault-Gallagher line put up 3 points against Vegas and 3 against Tampa.
Its not so much that Leafs were shutting them down as that line was only playing prevent and not actively trying to generate offense. Everyone but the Jets "shut" them down.
Context does matter. First things first, remember that softie Campbell gave up in game 7?..Those were the 3 points that line got. The reason you have "Tatar/" in front of Evans is that the Habs first line was getting wrecked so badly that Keefe didnt even work around the match up and the Habs had to blow the line up and ultimately benched Tatar.
I mean, you really think Danault changed his two-way game to get caved in in almost every way and just hope Price would start his Cinderella run playing Vezina level goaltending all the way to the final and Matthews would just end up hitting multiple posts with all the chances he got? You think he would want to get dominated on the boards worse than he ever has been in his career and end up with probably the most brutal 7 game stretch of analytics in his career?
Matthews ranking out of the 176 forwards with at least 50 minutes played in the first round this year:
Total Shots: 2nd highest out of 176
Shots/60: 8th highest out of 176
Individual Scoring Chances: 3rd highest out of 176
Individual Scoring Chances/60: 5th highest out of 176
Individual Expected Goals: 3rd highest out of 176
IndividualExpected Goals/60: 7th highest out of 176
Price going beast mode + a stupid amount of posts/near misses kept the injured Matthews from improving on his 5 points in 7 games.
Combine those numbers with his solid 5v5 underlying defensive metrics:
Goals against/60: 9th fewest out of 166
Overall Takeaways: 1st out of 176 by a mile
Overall Takeaways/60: 1st out of 176 by a mile
Best giveaway to takeaway ratio in the first round.
Here are Danault's 5v5 numbers against the Leafs:
CF%: 48.26
SF%: 40.10
SCF%: 39.82
HDCF%: 43.12
xGF%: 34.89
GF%: 0% (-1.59/60 goals against)
Danault 5v5 the rest of the playoffs:
CF%: 47.12
SF%: 52.13
SCF%: 48.35
HDCF%: 49.51
xGF%: 55.21
GF%: 57.03
Those numbers the rest of the way against the top players on great offensive teams (Jets/Knights/Bolts) are steller.
Matthews was by far the toughest matchup for Danault in the playoffs. He did a far better job against the other teams but in the end Price made a number of players good players look bad and players that were going through rough patches look better than what they were. When your goalie is standing on his head and you are winning, everyone looks pretty good I suppose. The Habs got a little of their own medicine in that Bolts series though as once you meet your match in net, the better team is going to come through.
