To illustrate my point
Top lines by TOI:
- Kucherov-Stamkos-Namestnikov
- Gaudreau-Monahan-Ferland
- Marchessault-Karlsson-Smith
- Iafallo-Kopitar-Brown
- Tkachuk-Backlund-Frolik
Top pairs by TOI:
- Jones-Werenski
- Giordano-Hamilton
- Ekblad-Yandle
- Trouba-Morrissey
- Reilly-Hainsey
- Braun-Vlasic
- Demers-Ekman-Larsson
- Brodie-Hamonic
4/5 lines and 7/8 pairings are the same as the ranking by CF, so it's more a byproduct of being healthy and keeping the same groups together than any measure of quality.
