I know we should not suggest rule changes once the competition is under way, but ...
I noticed I have home advantage in the next round, but I do not actually have any advantage!
How about if the Home team, by PM only, was allowed to change two of the Away teams predictions by 1 goal each. The Away team obviously could delay posting their predictions to help prevent that adavantage, but then risk forgetting or missing the deadline.
I do appreciate that adds a lot of work for you Boc, so maybe only do it at quarter final stage with a 2pm (for 3pm) kickoff deadline so that the Home team would have a chance to see and amend two predictions if they wanted to.
