Of course Leopards and Lions can kill a HB on occasion, they're much bigger than them! That's nothing against the HB. Eagles are pretty hard *******s too.
A lot of people support the HB because of his attitude, an attribute much misunderstood and undervalued by those who just vote for the biggest creatures every year without understanding what it truly means to be hard.
And yet seem to completely ignore that attribute when the HB comes up against a smaller creature with even more attitude.
