OPTION 2

I would get rid of offsides. Just remove the blue lines, simple as that. It would have multiple very clear benefits:
- less stoppages of play (okay, also less ad space, but we could compensate this with making some of the other stoppages a bit longer)
- less video reviews and goals being taken back -> less controvery, less time wasted, more goals happening
- less work for the refs -> more mental resources for the referees to focus on getting the penalty calls right
- it would give more room for creativity and different playing styles, which could lead to more variance in the way teams play
- it would probably also just in general make the game more offensive-minded and add more action to all parts of the ice
- would be interesting to see how teams would start playing power play and penalty kill, since zone entries would be easier and defensive teams would have harder time getting to a line change

In reality I'd say this is just an experiment I'd like to see done somewhere. It's very possible that there would be unwanted consequences that I was not expecting, and that could make the change negative.
