It's even far beyond that. They won the cup with Kucherov, Point, Stamkos, Palat, Johnson, Gourde, Cirelli, Shattenkirk, Hedman, Sergachev, McDonagh, Paquette. None of these players are particularly known for their ability to punish.
Most of their grit (Coleman, Goodrow, Bogosian) were added at the deadline. The Bolts didn't start the season off with the level toughness they ended up with during the playoffs. Before those three additions, the only real tough players on Tampa were Maroon, Killorn, Cernak.
But Tampa was also at a very different organization stage. They weren't a rebuilding team. They added grit as their cup window opened.
I am very comfortable in saying that Arber, Struble, Dach, Slaf are every bit as gritty as Maroon, Killorn, Cernak. Anyone including Sergachev and Hedman in that category should then be including Guhle and Anderson.
As the habs advance in their rebuild and space in the bottom 6 opens up due to expiring contracts, they will get more robust.
