So the problems with the Caps are
- Special teams
- Forward depth
- Defense depth
- Mental breakdowns
- The circumstances
See, it's simple what's going wrong. (1) goaltending sucks (2) star players suck (3) PP and PK suck (4) offense sucks (5) defense sucks (6) play in general sucks (7) reality exists.
So there you have it, the only thing holding back the Capitals from being great: everything about them is terrible. Breathtaking analysis from NHL.com here.
