Well Mack the Hammer was as tough as they come and he certainly was a lot bigger than the Tiger and he had a heck of a supporting cast that included "Hound dog" Bob Kelly, Don Saleski, Ed Van Impe, the Watson brothers, and Moose Dupont just to name a few! The Tiger had a bit of help but not much in comparison! But it's safe to say he wasn't scared....
I remember that series as well Cheapie, I was 8 years old and watched every game with my family at my grandparents, who were huge Leaf fans...
Here's a picture of Dave Schultz taking on the much smaller Tiger William's!
