What happens when there are multiple greenslip to be awarded? I think that would get very complicated. That being said, maybe this is something that they are looking at or some modification. On cursory consideration, looks like it could be made to work.
The way it is, it's a take it or leave it and move on to the next. Simple and effective. Plus, as a junior guy, I don't want to have my hopes dashed multiple times....
