Not the most highly skilled, but undoubtedly the deepest.
The Preds have no real weaknesses. They throw all 4 lines at you, have guys on their 3rd defensive pairing that would be #1s elsewhere, and have one of the best goalies in the league.
I see two ways the Preds don't make a deep run (defined by at least making it to the West Final or Cup Final):
1. Pekka gets worn out
2. They take lots of penalties and are unable to kill them all. The rough patch that they fell into in late March was caused by that. They took lots of penalties and got into 5-on-3s, giving up lots of PPGs.
