The Penguins have been too inconsistent. The followed up winning 10 of 11 by losing four of five and allowing at least five goals in four of those five games. That isn't going to get it done for a team with Stanley Cup hopes.
The defense needs work. They traded Jamie Oleksiak, who struggled, to the Dallas Stars on Monday and remain without Justin Schultz because of injury. Letang can't do it all by himself. Pittsburgh has also allowed a League-high 11 shorthanded goals.
