Idk, are they better than Kane, Toews, Sharp, Hossa, Versteeg, Brouwer, Saad, Bickel etc (when you look at the counting stats there remember that scoring is up almost 20% since 2017ish)?
2016-17 Penguins with Crosby, Malkin, Kessel, Sheary, Hornqvist, Bonino, Guentzel, Rust.
I'm not sure they have a better offence than the peak Tampa years either. 2018-20ish you have prime Kucherov, Stamkos, Point, Gourde, Miller, Johnson, Killorn, Palat, Cirelli.
I think the Florida group compares but doesn't clearly exceed those. Strictly talking offence here obviously Barkov is a transcendental two way guy and those guys bring other value beyond point production.
