2nd line would be getting relatively sheltered offensive minutes in this scenario. Every other line there is fully capable of going up against any opponent line IMO, which allows the flexibility to shelter this one.
Disagree with the bolded. Kyrou and Schenn played a decent amount together last year and generally work fairly well together IMO, especially if they are starting in the o-zone. Schenn and Neighbours may not be able to keep up with Kyrou on the rush, but once in the zone I think all 3 could work quite well together.
