The Jorgic issue only came up because he made the finals consecutively. He was beating most of the europeans with twice as much firepower as him in their backhands consistently. My point still stands, if you have glaring weaknesses and some outdated ideas, you can still make top 10 in the world.
Now he's more well rounded and has advanced into the top5, but he only needed these aditional skills for that very final push
You are now beginning to sound to me like those people who talk about Dima being a former world #1. As in, let's forget all the footnotes, just look at the number. He was a former world #1 so that proves that he could get to world #1 with his style.
The conclusion is that one can get to a high level with relative deficiencies is okay and not even debated, we are not arguing top level here, but how deficiencies make your performance unstable and unreliable, especially in big matches./events. The Jorgic issue is not the only issue that shows Trul's limitations and instability. He has no European singles titles. So how are you beating most Europeans but have *no* big titles? He should have at least one if he was as dominant as you claim. Why would he lose to his teammate Falck in an European Champs?
Moreover, beating most Europeans doesn't make you a top 10 player strength wise. It can give you a top 10 ranking, but I would argue that even then, most of Trul's top 10 ranking came from the WTTC silver, and one can analyze the quality of wins he had in that event and decide how much of it was skill and how much of it was luck. It's easy to forget that he played an injured Boll in the semis and before that, barely got past LJH and Franziska. And without that silver, there is no way he would have been top 10. And that silver was made possible because he was in the half of the draw that had only Zhou Qihao while LGY, LJK, Hugo, Wang, Fan Zhendong etc. were all on the other side.
And yes, it is possible to have glaring weaknesses and still make top 10 in the world. It is just harder to do so and win big titles when everyone is preparing for you. BTW, if Hugo had Truls draw in 2021, he would have had a silver. No doubt in my mind, took an amazing comeback from Liang to eliminate him. But he just wasn't lucky. Truls was. Hugo has short game issues relative to his level. But he was clearly a top 10 player, even if arguably overrated to some.
