Ok so my original response was deleted. Obviously the mods get offended by any cross country discussion but are happy for GerrySA mark4 to continue his merry way.
You actually said Wagner would find him out and he was limited. All ill say is - if you dont like the word 'currently' then how about this - Dom Sibley will FINISH his career with a higher average than any NZ opener in living memory. Probably any opener in the history of NZ cricket. Facts upon facts. No joking about it.
"Currently" Jack Leach has a better opening average than all NZ Openers
We certainly struggle in the Opening batsman category thats for sure. Tom Latham I think will end with a very good Career though. We're not as fortunate to have such good openers as English cricket seems to keep producing.
I think you misunderstand what a fact is, for example when I said Wagner would find him out, thats not fact thats just me making an observation based on what I have seen from his leg side play it wont become a fact unless it happens like if Sibley ends with a test record above Latham (It could certainly happen, but its not a fact).
The fact is England Openers don't last long and Id be surprised looking at Sibley and his lack of scoring ability in certain areas plus the fact he gets beaten a lot, knicks towards slips, struggles when the ball is around his hip that he wont get found out by good bowling (No not NZ bowling as we are clearly trash in your eyes) but Australia et al. He is limited, look at the field they set for him against spin. Cook was limited but that doesn't mean he's not great.
Stop living up to your sterotype...
