Disagree. He does basic things well, which a lot of our players don't. Main one being, he can stick a defender before setting up his outside man.
Paisami is massively explosive but he's still not particularly technical (cute grubbers aside). I think having a slightly understated player on his inside will only compliment him.
Having someone else with a boot also seems essential if you are starting JOC (James O'Connor) at 10.
Your assessment of "form" for 10 - 12 - 13 is spot on I think. But it does show how the theme
"just put the best player in each spot in that spot!" isn't necessarily the best selection.
I think that Rennie will very much have JOC (James O'Connor) and To'omua in mind for 10-12, I'm not entirely sure which way around. I'm not convinced that Simone has shown what he needs to in order take the 12 - plenty disagree and they may be right. Also keep an eye on Perese. And I'd imagine that Rennie is thinking hard about To'omua, don't think it's a slam dunk.
I'd go close to rating Lolesio as the best of the new 10s coming through. He will struggle to oust To'omua/JOC (James O'Connor) simply on the grounds of experience and cool head. If those two manage through to RWC (which is likely) there may well be someone else on the horizon. I'd imagine that Lolesio will get his chance but not in the first XV very quickly.
I'd also suggest taking another look at Paisami - lacking "technicality" has been true but he has been working on it with excellent people. He might not be the full quid right now but he is definitely headed that way.
I think my selection would be JOC (James O'Connor) - Simone (with lots to prove) - Paisami. And I'd be tempted to try Perese at 12 at some point, maybe the B team from the bench.
