When you get booted from the game for fighting there isn't too much to work with outside of a bit of niggle.
Not true at all. Most leagues outside of North America give you the boot if you fight. That doesn't mean that a) fights don't happen and b) there are not huge rivalries. In fact, it means that any fights that do occur are very heated, because you know what's at stake. You don't get the painfully scripted and "tactical" fights like you get in the NHL.
For example. That was a huge turning point in the match.
Furthermore, given all of the concussion dramas that the NHL has experienced in recent years (along with other sports) I wouldn't be surprised at all if they started booting fighters too.
And finally, rivalries are built on more than just fighting. They generally come from a mixture of close encounters and proximity.
