IMO this is the biggest series of the year for the Sioux and (obviously) sets the table for the endgame. A sweep puts them in the driver's seat for the Cup, first round home ice and all that. Losing two to the Pios might a deal-breaker. Denver is skilled everywhere on the ice, scores well and defends excellently. Big, big test for the home team.
I'm all about risk vs. reward; this is a high-risk series, with a huge, huge payoff if the Sioux can get a sweep.
