The Stanley Cup playoffs opened Wednesday. One of the five matchups was in the pick range. But underdogs emerged victorious in three of the other four first-round, first-game matchups.

Heavily favored Tampa Bay was one of those losers. That's a huge break for Boston. The Bruins could be vulnerable against revenge-minded Toronto here. The Maple Leafs nearly upset the Bruins in the playoffs last season losing in seven games. This time around the Maple Leafs are more experienced and have added superstar John Tavares.

Toronto holds a speed and offensive edge. The pressure is on Boston, too.
