True.
And an other example :
Actually i'm traing Jumpshot for PG and SG.
So i have buy only 18 y/o because it's faster..
But i have a 22 years old SG, NT player of Tounes. I'm training too but it's slow..
So, team who got older player than they could have ( 22 for exempale instead 18 y/o ) it make more difficulty for the team, but it's better for the National team.
We can have somes advantages of that ( like reducing wages )
