Well, I used to play a mean defence for my old soccer team, a year back. I'm amazed at some of the stuff I've pulled off without getting carded. Thats what happens when you get really agressive defenders and terrible referees, I guess
But I could probably take on a modestly agressive bear. Probably not a grizzly, but some middle of the road bear. I mean, it would be a challenge, and I'm sure I'd get a few battle scars, but I'm pretty confident in my kicking abilities
