Recent game I watched with the Flames/Coyotes. Coleman hit Crouse's teammate in an iffy hit. Crouse grabbed Coleman by both his shoulders, towering over him and had a intimidating talk. Coleman wouldn't even look him in the eye. Teammate wasn't hurt/got right back up and play was still going but they were in the corner on the other side of the ice for a good 10 seconds.
Not a frequent fighter but he has gone against some bigger guys like Lowry, Maroon, Mayfield. Even stars like Landeskog, Pacioretty. He does bring a pretty big physical edge.
