Boston hasn't played in a week due to COVID-19 protocols. The Bruins still may be minus starting goalie Tukka Rask, who has been out since March 7. 
I'm factoring that the Bruins are going to have some rust. That won't be the case with the Islanders. This is New York's fourth game in six days. The Islanders happen to be 7-0 the past seven times when playing a 4-in-6 situation. 
The Islanders have been one of the hotter teams in the NHL winning 10 of their last 12. They have the No. 2 defense in the league. They also have defeated the Bruins in each of the last four meetings.
