Despite being short-handed due to injuries and COVID-19 issues, the Capitals have managed to go 6-3. The Capitals' first eight games were two against the Penguins early in the season when Pittsburgh was struggling, four games against the Sabres, who have a losing record, and two games against the 3-6 Islanders. 
Finally the Capitals stepped up in class this past Saturday. They nipped the Bruins, 4-3, in overtime. 
I don't see the Capitals doing it again in this Boston revenge spot. The Bruins scored three of the last four goals. They outshot Washington, 43-23. It was clear to me the Bruins were the better team. 
Alex Ovehckin did return after missing four games due to COVID-19 protocols. But the Bruins also got back their superstar, David Pastrnak. He played more than 20 minutes, while Ovechkin was limited to fewer than 15 minutes of ice time. 
The Capitals still could remain short-handed. Justin Schultz, Lars Eller, Evgeny Kuznetsov and starting goalie Ilya Samsonov are all day-to-day. 
Washington has lost 12 of the last 16 times following a victory. The Capitals are in action for the fifth time in nine days. All but one of their last seven games have been decided by one goal. So there has been a physical and mental toll on the Capitals. The Bruins are an elite team that should take advantage especially given the situation.
