That's the good side for Mtl to play 2 teams with little stake at play. Toronto has nothing to gain, and Washington may try to push for #1 in the metropolitan, but they only need 1 point in their last 2 games.
Overall, both those teams would benefit more from starting the playoffs fresh and injury-free. Most likely, any player who is tired, has a small bruise, lingering injury or anything like that will probably sit, and they will probably send their backup goalie for the last 2 games. On top of that, just like the game against Tampa, the word is to avoid injuries at all cost and not do anything stupid.
The only players that you will see showing any sort of effort are the replacements who will try to impress to earn a spot in the playoffs.
That being said, with Montreal likely facing Tampa Bay in the first round, I would rather take the 3% chance of picking in the first 3 spots, and enjoy TVA Sport missing another playoff run, then getting out in 4-5 games.
