Essays / Violence in soccer and hockey - Need advice [3]

Hi guys,

I recently got an essay topic and it's the following:

"compare the violence in hockey (mainly on the ice) to the violence in soccer (mainly in the stands).

So basically to compare the fact that violence in hockey happens mostly between the athletes and violence in soccer happens mostly between the fans. I don't quite understand how I could structure this and what my points of comparison would be. The only comparison I could think of is that sporting events themselves promote violence in their environment irregardless of whether it occurs on the ice or the stands.

I am supposed to list implications, comparisons, other important points, and points in trying to solve this.

Any help would be greatly appreciated
