Preds should be on their heels the entire game, and it can be expected that San Jose's offense only gets stronger from here on.
These two teams are heading in opposite directions right now. Nashville is really struggling on offense especially with Martin Erat injured this whole time (he may return tonight but certainly not at 100%), and now Cal O'Reilly might be out. That pretty much limits their main scoring threats to David Legwand and Sergei Kostitsyn and then, Shea Weber and Ryan Suter on the blue line. With that in mind, understand that the Preds should most likely resort to a defensive game like they have (unsuccessfully) on their entire road trip. Also, coming off this road trip and heading back home, they should be a little sluggish to start.
The Sharks are the last team that the Predators will want to run into right now in their given situation. San Jose is just starting to heat up, and have already made two top end, good defense, Eastern Conference juggernauts (Boston and NJ) their victims. In reality, Nashville should be a cakewalk. Preds should be on their heels the entire game, and it can be expected that San Jose's offense only gets stronger from here on.
