St Louis was one of the best teams during the second half of the season, and I think everybody knew the Jets were in for a tough series.
Aside from Columbus shocking the hockey world, the Islanders, Hurricanes, Stars, and Avalanche have also been impressive so far. I didn't expect Carolina to give Washington much of a challenge, but they have made a series of this. The Stars are giving Nashville a real fight too.
On the other hand, while Tampa Bay is certainly the biggest bomb in the playoffs, the Penguins and Flames are not far behind. Calgary still has a chance to turn things around, but they haven't looked like a #1 seed, or a team that can win 3 straight. They better get it together fast. "Johnny Hockey" has certainly not been "Johnny Playoffs" so far.
