I’m not following the comparison between the World Cup and the test team. To clarify, I’m talking about Umar Amin being in contention for the red ball team. I don’t see him having a role in white ball or the odi World Cup.
He is playing first class cricket and topping the charts. If I follow your post, isn’t that what you’re advocating for? It contradicts your next statement that you’d rather bring back Fakhar Zaman who doesn’t really play any FC or county cricket, and he’s the same age as Umar Amin which you also see as an issue.
He will fail miserably in red ball.
What people fail to understand is that topping charts and performing doesn't entail success.
Sohaib maqsood was performing in domestic but failed on his return comeback, Usman Khan is the 2nd coming of Bradman in psl but failed in international.
Technical prowess matters and this is something psl is clueless on.
A batsmen can improve on certain things, for example even though babar has regressed, He can improve against spin since he just needs to improve his range of backfoot strokes against it, otherwise their isn't anything wrong with his footwork.
People like rizwan or Usman Khan have no ceiling to improve and will always be medicore at best because their entire stance, Footwork and the cricket style they have spent decades building is now unchangeable. And unfortunately rizwan footwork, range of strokes and stance includes being a legside hack, while Usman Khan has possibly the ugliest footwork I've ever seen.
It's why I can tell saud shakeel will succeed and why someone like maqsood can't.
Umar Amin is no different, technique and shot selection wise he is extremely extremely poor when it comes to driving and just overall struggles with pacers who tend to bowl below waist height.
He's good against spinners, Can play bounce well but as soon as a bowler bowls below waist height, He'll likely play his usual lofted drive and get caught out.
International is a completly different ball game from domestic or league cricket where people like azam khan can function
