Over the course of a larger sample size, there tends to be a certain asymmetry in the playing time of PP units that tilts total ice time in favor of first line/unit players. I think a lot of specialty team play in general hurts Mantha's playing time. For this reason I am more interested in comparing ES shifts than anything if we are going to talk about relative ice time.
Yes, and they received the 2nd line ES time. Frans and Helm only had about 11 mins of ES.
The thing people complaining about Frk and Abby randomly swapping need to understand is that it usually comes after a PK and Blash wants to get Abby a shift. Is that ideal? No, not at all, but Abby isn't PKing much outside of a killer being in the box anymore.
That's one thing we don't see for a player like AA, much to our frustration, when his linemates sat after PKs he had to wait til the next shift with them. Which is absolutely stupid because AA can break a shift wide open, Abby can just go out there and try to compliment his line mates.
