Carter is not as good in the set piece as Horwill. If he was he'd probably be the Brumbies line out leader. He is also not as good in the scrum. He is also nowhere near as experienced.
You want to know why Carter has only been "below average this year"?
Because it's only this year he's had to back up from a season that finished at the start of December. Where as Horwill has pretty much done it consecutively since 2008.
Some of these less experienced options look great at Super Rugby level. But they're coming in fresh. How many Wallaby players take half the season to really get going? Look at Carter, Jones, McMahon, etc. who really have been below what we considered par for them before this season.
We think these new players are going great guns but then suddenly they get smashed at test level, then back up the next season shithouse because they've hardly got a rest period and have done half a pre-season. So when we get to the point that we compare apples with apples (players who have come into the season with similar preparation), they no longer look like the potential star we thought they were.
Now it's all well and good if you are going to wipe the slate clean every test season and start again with new players and not want to build on the previous season and squad.
But if you don't then you'll find when all of these players have to regularly deal with the rigors of a test season, they aren't exactly the player we really thought they were.
TWAS as you know trying to compare players on an internet forum is full of subjective opinions usually based on little more than which player plays for the Super team the particular fan follows, or on a reduced sample because some of our selectors here either only watch the games involving thier own team or don't have the opportunity to watch more because they don't have access to Foxtel (as many, many posters complain about).
So I can accept your support for Horwill but I do have some subjectively based misgivings about your take on some of the options, either for lock or for elsewhere.
For instance, I really don't think Luke Jones has struggled to find form this year, and I strongly believe he has been playing better than Big Kev. Then, McMahon has missed a few games through injury, but when fit I believe he has been as good as he was expected to be, though playing at No 6. I don't think either of these players fits the description of having been below what we considered par for them before this season.
In Sam Carter's case, I think there is a widespread notion amongst followers of other teams that he hasn't been performing this year. That is simply not true - the notion imo has been formed by posters who probably haven't been following the Brumbies as closely as they do their own teams, if at all. And it gets repeated by others with a particular favourite they want to push or by those again who either don't or can't watch all Aus teams play. Sam has been going good doing what he always has done. He and Simmons are just about interchangeable for the skills they bring to the game.
I think the possibility of Carter going to RWC will frest on Cheika's thoughts about whether he wants two locks of such similar skillset. If so, then Sam will tour. If not, but wanting a more aggressive, in-your-face type of lock to replace or back up Will Skelton, then he'll go with one of Coleman or Arnold regardless of inexperience. In any case, I will be surprised if Kev gets a gig at this RWC.
For the record, I watch each and every game involving Aus sides and most involving NZ sides. Maybe I should get a life?
