All teams trap and all teams do it every game. Difference between doing it in certain situations and having it as your main strategy.
Let's challenge that notion of a main strategy.
- this assumes that a team selects 1 main style of play for every opponent and every game AND that this style of play is the same .... if that's true, why have scouts and video analaysts?
- In a hockey game, you are likely on the PP for 6-10 mins a game. You are on the PK for 6-10 mins a game. This is up to 1/3 of the game on special teams. You also roll 4 lines with a variety of skills for the rest of it.
I'm not at all suggesting it's unlikely that a team may set up a trap right from the get go. A trap from the drop of the puck would make sense to me if you are coming off a road trip or have injuries. But I don't think a team picks a style of play on day 1 of preseason and sticks to that forever.
It's more realistic that they practice different systems, breakouts, d coverage forecheck, etc and employ them on a game by game or even shift by shift basis. On the latter, maybe you Trap Crosby's line but why bother doing it to the 4th line?
I think teams get labeled as trap teams (or possession teams) in the court of popular opinion which in most cases doesn't fully understand the game.
And let's be honest, how many that weigh in on this subject have spent time watching any team other than their own?
