Just musing on size of back rowers:
Force is proportional to mass x acceleration. I think that with Simmonds being acknowledged to be very quick from a standstill, that he'd hit any contact with as much force as someone heavier but with less acceleration
Momentum = mass x velocity. To make a dominant collision, you need to have a higher velocity. (yeah, run hard and straight...) Slower service from the scrum, meaning the ball is passed to a player standing still, will result in fewer dominant collisions. You also want to be hitting a defender who is standing still (as their momentum will be zero) rather than one coming forward, whose momentum will be in the opposite direction to that in which you want to go.
Conclusion: the most important factor in making headway is actually swift service to a player moving forward who then accelerates into contact. Bigger is better, but only if velocity and acceleration are present first.
Slow service eh? If only something could be done about that...
