Rugby

I may be old fashioned. But the forward lean of the front row seems to increase every season to me. The way the props are set-up, its had to see anything other than a 'hit' being possible. Unless your second row is super human.

I totally agree if you look at the position that world class props end up in once they are engaged it is actually impossible to hold the scrum up watch this video:

Everything about his body position is set up to provide drive forward, not to prop.
