No, never played in the NHL, though that wasn't the point I was trying to make whatsoever.
Pretty much anyone who has ever played that knows jumping around like that is frustrating.
Nobody likes having uneven lines, nobody. There is a reason it is not common in the NHL, it's a gimmick.
If you need to play your stars like Stone or Duchene more, do that. Just don't do it by having 2 spare forwards without a set line, that is nnoying as anything for all players involved, again, anyone who has experienced it AT ANY LEVEL in case you misunderstand again.
There' a reason it's said that the lines are messed up as soon as someone is kicked out of the game.
