Hahaha! Sorry I laughed out loud reading the title of this thread. To me, class is forever. Some of these older cricketers you are mentioning will take 2 matches or less to rape our young team. Maybe fail in the first one, due to an off day, but then mercilessly punish the team in the 2nd match as they find form.
Technique cannot be replaced, and the older folks got it.
But no, I see what you saying. You are banking on the other teams not to produce such technicians in future. But what if they do? We better have plenty of our own by then.
The day con man extraordinaire Mushfiqur is dropped from the team, that is the day I will know we are not pussyfooting around anymore.
