yeah thats teh beauty of being a 4 line team. You dont need 1 or 2 or 3 guys to be ON all the time in order to be successful. Guys go through slumps..it happens...guys like like crap. you just bank on the fact that of your 12 guys in your lineup...if at least 1/2 of them are playing terrific, you'll be fine.
If youre a team built completely on 1 line...like the Alfie, Spezza, Heatley line of years gone by...if they go cold, you are beyond screwed.
The Penguins are like us, but on Steroids. 3 First lines. We've got 3 2nd lines.
