*Hands you Pandora's box*
There have been more than a few times I myself would like to have seen a replay on a dicey ruling. But there are many concerns. Having it just for the Elims would be problematic.
- Match play varies a great deal between Qualifications and Eliminations.
- Elims last 6 hours or less.
- Takes up space on the field/truck where it is at a premium.
- Has to be maintained so it doesn't crash.
- Finding persons neutral enough to operate it.
- Challenges already take up a lot of time.
- Lessons are lost by teams not learning how to argue their case.
- Costing a team a valuable time out is problematic.
The short answer is that while it is a great notion, I cannot support it.
