Vaibhav should have been given more time in India A before being picked in the senior squad.

NO my opinion HAS NOT CHANGED. This was always my opinion, regardless of his result. Even though he's such a good talent, he definitely hasn't faced 145+ in U19 matches much. In the IPL, anything you bowl gets bashed so pace won't matter anyway.

But the issue is, in SENA, a 140+ ball is extremely tough to bat against if you've never faced that speed there, and sending him over so soon might've exposed his struggles against Archer.

This is why India A is important. A lot of A-Team bowlers always clock 135-140 and in SENA it's a great thing for practice. There's a reason why most people go through the A squad for a while before getting into the senior squad.
