As has been said they don't need the extra space. I play both codes. As a RU Centre and a RL Second Row. In RL it is possible to break fast from the scrum, however in RU the Forwards seem to take a eternity at the lowest levels and so leave their Backs in the sh*t.
I once didn't break out of the scrum fast enough from the 2nd Row and let a Try in as they were only about 20 metres out, so beat myself up about it but it happen... Giving the attacking team an extra attacker is really unfair on the defending team.
Gaz, I think you may have misunderstood the 'over the dead-ball line' and charge down Laws? As they'd both give the defending team the advantage, as if they charge down the kick the tackle count remains the same, so they don't need to worry about the tackle count getting wiped, and if a 40/20 attempt goes out in their 20 having been kicked outside their opponents' 40 they will get the tap on their 40.
