The difference with Pit is that they have an elite player to carry each of the top 3 lines.
Kings have Kopitar/Carter/???? Lewis? Shore? Brown?
You can get away with playing a plug with Crosby if Kessel is tearing the other teams 3rd D pairing apart.
I get what Herby is saying. There is a complete lack of depth. If Kopitar goes down, it would hurt no matter the depth. If Martinez goes out this thing turns into a train wreck. Losing your #3 D shouldn't cause the team to implode. Also if Carter goes out the Kings are running rookies or Lewis 3 of 4 center spots. I guess Shore has a year so isn't technically a rookie. This could get ugly quick if the Kings get any sort of injury bug this year. Say Martinez gets banged up and Toffoli gets mono.... That's like MTL -Price. Injuries happen in hockey.
Edit: re: Clifford on the top line. Half way through the year of showcasing Brown I'll probably be demanding Clifford get a shot on the top line because I won't be able to take any more.
