I've heard others echo this exact sentiment about Krebs as the 3C, I think we're starting to get caught up in line numbering semantics. Most teams have one of the following models for ice time distribution and roles at even strength:
- Top Line
- Middle 6
- 4th Line
or
- Top 6
- Bottom 6
Two years ago we deployed the first model (actually it was more like a top line and bottom 9). I think last season and moving into this season we're trending towards the latter model. So when labeling Krebs as a 3C or a 4C, the term "distinction without a difference" comes to mind.
