Not sure I can come up with 10 off the top of my head, but I'll give a few for the Leafs that I can recall off the top of my head since I've been watching (born in '73)
Clark vs Probert (Probert's first game back in Canada after his legal troubles)
Domi vs Ulf (you're welcome Cam Neely)
Orr KO'ing Carkner (many times in one season)
Belak vs Janssen (after Cam ran Kaberle)
Orr destroying McGrattan (bloodying him badly)
Clark vs McSorely ('93 playoffs)
Orr dropping John Scott?
Potvin vs Hextall
So many crazy Toronto/Buffalo, Toronto/Ottawa stuff from late 90s, early 2000s. Plus, lots of Norris Division stuff with Det, Chi, Minnesota. Domi has a ton too - taking on 2 Flyers, his battles with Rob Ray, Probert. Plus more recently, Colton Orr basically beating everyone.
