For me, it's frustration because the Pens have just moved on and are resting now so if the Caps do win the series, we want this over with ASAP so they don't get more banged-up. And thinking/wondering if this series could have been over already feeds that frustration. Those who believe Holtby should have been put in earlier (in game 1 or 2), well, yeah, it's frustrating. Until the next game rolls around and we all have to wait for the outcome, that frustration just continues to eat away at us. Thus the back and forth.
