Without quoting everyone, is it fair to say there are no "soft match-ups" in the 1st round anymore, but there are certainly more favorable match-ups from a style and team composition perspective?
The chaos of the 1st round to me favors the faster heavy-forechecking teams now. The days of a 1-4 neutral zone trap team sitting back and grinding out 1st and 2nd round playoff wins against a heavy forecheck are over. You look at last year's match-up, the Panthers forwards forechecked hard while their D (beyond Montour) sat back and just played it safe and conservative allowing the Panther forwards that freedom to unleash the forechecking pressure.
Meanwhile, you give me a more methodical defensive team similar to the Bruins and the Bruins probably win that series 8 times out of 10.
Bruins also struggle more with "shot volume" teams. Once again, Florida is an example. One of the best ways to combat the Bruins collapsing zone D is to just throw everything at the net. It pulls guys out of position on loose pucks/rebounds/deflections/missed shots. Meanwhile your likely to get a friendly deflection or bounce at least once or twice a game.
Conversely, a team that likes to pass the puck around the perimeter and maintain possession are right up the Bruins alley because the Bruins are fine allowing the team to keep possession as long as they are kept to the outside and out of high danger areas.
