It's a fair call and not a Kent fan....actually the opposite.Kent mentioned an interesting stat on 360 - the Riff have the lowest post-contact metres of any side in the comp!
Apparently because they are more focussed on getting to ground with a quick ptb than struggling to make a few extra metres...
Helps when you have big ass props with excellent skills I guess...
the momentum of the ruck is what generates the opportunity to really open up that "big play" and by winning the quick play, it gives the attacking formation time to execute with space and cohesion and on the other end, the defence is still backing away and has no time to reset, only panick in a confused formation that can be picked apart.
