I liked your post but every one is leaving out Faletau who in my opinion is up there with any of them, is it because he's playing in a welsh team?The better number locks, props, 8s or flankers I played with were hardly running in tries all the time, if at all. Their contribution was generally felt elsewhere, like blasting people of the ruck, or being at the bottom of it, where the ball was. All, so that fellas like me could score the odd point, or feed it to the 3/4 line to have a feast. Not saying they never scored points, but if they did, I'd treat it as gravy as opposed to requirement.
If I was picking an 8 today, I'd still pick Read. Stander would have a good shout.
