Bit of a mess at the moment. I noted earlier I wouldn't mind for when it came to tries of they reworded the laws such as there was always a need to prove a try shouldn't be awarded, still pondering that one.
The change I might actually make prior to handing the call over to the TMO is for the ref (following consultation with the TJ) to state what the onfield decision is, then the TMO would need to establish a clear reason not to go with the onfield decision. As is the refs are not required to specify their position, so there's no accountability being established, nor primacy for the onfield officials. So if the TMO agrees with the ref decisions stays as is, if the decision is clearly wrong the ref can be advised to overturn, and if it's not clear it's a bad call from the ref we stay with the onfield decision. So some similarities with cricket's DRS, and if Skand reads this he may note another sport it'd be similar to (but we'll ignore that as this is clearly original thinking on my part)
