I have two more questions. One I haven't quite figured out the structure, i.e. do centers generally try to stick to a certain area of the ice or is it more everyone just roams. Are centers generally your top assist men and have more assists than goals or is that just Vancouver where H. Sedin and Kesler both have more assists. It seems that the wingers, Burrows and Sammuelson for example, are more kind of goal poachers to use a soccer term.

And two what is the offside trap? I finally have figured out the offside rule pretty comprehensively but am still not sure about the trap.
