Hmmmm... perhaps I should be more specific on the offside thing.

If there is no offside call, there is no call to challenge. That's the can of worms with an offside challenge whether it results in a goal or not.

Same goes for cards. I have seen cards issued that were obviously incorrect on video replay but NO WAY would I want such reviewed by an off field ref.

But, those are all details for consideration. Goal line reviews... I say yes.

In the Yank system, some "plays" are automatically reviewed without the Red Flag challenge in the final two minutes. I dunno if such would apply in football... can't think of any cases off the top of my head.
