In a series that most NHL fans thought would be perfunctory, the Nashville Predators and Carolina Hurricanes have made for some excellent hockey viewing so far. While the Hurricanes took a 2-0 lead in the series, the Predators kept Games 1 and 2 interesting until the end, and then flipped the script to claw their way to two home victories. A first-round series widely thought to be a mere formality suddenly heads to Game 5 in Raleigh, and both teams are desperate for this win. What could help decide who leaves PNC Arena with the victory?
