For those who wish to implement instant replay in FIRST, I suggest you do 1 of 3 things:
1.
Volunteer as a referee.
VIMS is up and running. Sign up for a regional, help out, and learn from an experienced head ref. Your opinions about instant replay will become more credible if you are an experienced FIRST ref.
2. Create an off-season competition and implement tweaks to FIRST's rules as you wish. If you want to add instant replay to the game, go right ahead. Just make sure the teams know of this adjustment when they sign up for your event.
3. Convince someone else who runs an off-season event to implement instant replay. Offer to run this system for them, by providing the plan, equipment, and implementation details. Don't just say "you need to do this", but rather offer a solution and provide the resources to get it done. Also, don't assume that if you offer a complete package that this will be accepted by the people hosting this event. (the people who put on these off-season events have enough to worry about without this as an additional thing)
Reffing a FIRST event is unlike being an ump or a ref at any other event. Where else is a game invented each year and over 1000 teams play this game within 3 months of its birth? Game interpretations and rules are not always black and white. Instant replay will not solve disagreements with calls, it is as simple as that. If you do not understand this, please look to doing items 1 or 2 above.
