I wasn't saying Valetini is better or worse overall, I was just giving some substance behind the workrate concerns. Ultimately any discussion as to the overall contribution will come down to value judgments. I was giving Wilson and McReight as two yard sticks on work rate to compare to (and also likely being his back row competition for the weekend). Tizzano in defense was insane making a tackle every 4 min, while Samu the other way was quite lacking in attacking touches having nearly 15 min between touches. I think Valetini still goes missing for too long too often, but I would love to see him lift his work rate to match that of Wilson and retain his impact, obviously Wilson has slowed down since his blistering pace last year, but interestingly he has been turning it up coming to the back end of the season.
Lineout wins I think are often deceptive because that only really shows how often the team throws to you, as an example McReight is very capable as a lineout jumper but ASY (Angus Scott-Young) has bee largely taking that role as back row jumper for the Reds, Wilson is probably more capable but even more useful running the ball so gets used there.
I agree Valetini has this year made a lot more impact with his involvement this year, I just worry that at Test Level he goes missing again, his level of impact is broadly where it has been where he has been capable of for a number of years now (IIRC 2018 NRC he really burst onto the scene). I would really like to see him get his work rate to more around that level Wilson has had this year, and for him to be one of those players you say stood up for his team when they are under pressure, that I haven't seen him do yet (again I didn't get to see the Brumbies vs Force) but maybe he did it then. And I would LOVE to see him take that step in the Grand Final! If he leads the Brumbies to a win then I'll be calling for him to get a Wallabies start. But as I said I think at this stage it's safer for the Wallabies to start Wilson and have Rob in that Uru type impact player role and he's extremely well suited to that too.
