Not real wild about the "ejection" category. You are already penalized across every stat category if a guy gets ejected. Now you will have the additional burden of probably losing an additional category. Best case scenario it will be a wash if the other team gets a guy ejected too.
Now if you got credit for the most ejections and that is how you win this category then that might be kind of cool. It would offset the fact that you are hurt in other categories by losing a guy and could be a wild card category that could turn the game around late.
