Never said anything about height. Experience certainly counts though and Hooper has minimal at jumping in line-outs.
Like you said, he's slow off the mark and easy to read by the opposition.
Maybe Moore knows this and throws lower?
I think even McMahon would be a decent option in the line-out given he takes quite a few in super xv. Not the tallest guy either but effective.
I just picked that lineout because it was the first one. We lost a couple more in similar fashion.
I didn't say Hooper was slow off the mark. I said our lineout moves in general were slow. It was like watching a team going through the steps in slow motion when practicing them for the first time.
It didn't matter who the jumper was, it was easy to see who was moving around and was going to get it and where it was likely to be thrown. Unless the throw then hits the jumper at the top of their mark (and therefore clears any jumpers in front of them), it is easy to pick off as happened to us several times.
It came down to execution in my opinion, not the number of jumping options.
I think a reasonable amount of the blame rests with Moore and Simmons. The lineout improved when both of them were off the field.
