Does our T-20 success mean that our batsmen are basically tulleybaaz?

All your points are valid, however my comment is just about the current playing XI. Are all Pak cricket players (international, domestic, gali-mohalla *types) *tulleybaaz ? NO !!!

Pak is definitely a better bowling side than a batting one - no questions about that. Although I still think that the current lot pales in comparison to what Pak had in the 90s...There is just not as much that separates Pak bowlers from the rest :)
