Everything happened so fast (just about three minutes), everyone in the stands was reeling. I guess the good news is that the power-play didn't allow Richards, Gagne or anyone else to strike shorthanded, and, in fact, the Capitals had several excellent short-handed chances.
The bad news, of course, is that if they could have followed through on any of those short-handed breakaways (Backstrom's, Steckel's or either of Laich's!), the outcome of the game likely would have been much, much different.
