if people start blaming 4th liners as reasons we're losing games consistently its time to take a step away
4th line isn't the reason they can't win a game. Not having a full 4th line is certainly a contributing factor, though. Honestly, it does help to have decent players on the 4th line. Guys who can play more than 3 or 4 minutes and can chip in with points or by drawing, not taking, penalties occasionally.
