Storm will absolutely treasure their challenge... because they know it will be tight and they know the rule book better than the refs... especially how to exploit it.
I don't know if we have enough smarts/control across the team for them to know whether it's definite overturn or a 50/50 and they feel hard done by.
Broncos should just put a rule in place that if we're in front we're not using it... unless it's one like "did you touch it or not"... they should know if they've touched it, and if it's not clear then bunker will call it inconclusive and retain.
If it's a 50/50 on a strip or on a blocker/escort, etc. just leave it and defend... especially if it's in the first half.
If it's the second half and we're behind then you start considering for the 50/50's, but it needs to be treated like gold... because if the ref isn't calling penalties then it might become crucial later in the game.
