It is an interesting topic. 
Though I am a little concerned that this is discussed in the public forum, in the interest of our two NT coaches who are not in our FB group, will discuss this openly here:-
I look at it a little differently.
Considering that we don't have that many local trainers to begin with, I am thinking we don't really have that much to choose from in terms of pure U21 players. I have limited experience in U21 roster and skillsets, but from the time Ethan was playing in the U21, it does seem like we don't really have much of a choice with regards to getting a roster filled with $20K players compared to countries with higher userbase. Based on this, I feel the U21 coach is already trying his best and will continue to make do with whatever he has available in his roster (which has a roster refresh every season!). 
So it is not really about having an U21 team consisting of PA and below potential. For me, it is more towards every manager will train a player that will best fit his team. If the manager is hoping to contribute to the NT (be it U21 or NT), then a training proposal can be shared (this part the potential will play a big role as to what type or training is proposed) but still no guarantee for a spot in the NT. But when these players, irregardless whether they are starter potential or Hall of Famer potential, reach 21 (or maybe even 20), the U21 coach will be the one to decide which player will best fit the NT roster. Focus is on skillsets not so much on potential for NT selection. If there are two players with similar skillsets available to the U21 coach, then in the interest of the NT, the better option will be to opt for the one with a higher potential to enable a slight experience advantage.
I do agree with Westri that if a certain player exhibits certain potential for NT (both starting skillsets and potential), the training proposed should be optimised for NT. 
But of course, it is certainly still the manager's choice whether to follow 100% or to adjust according to his situation (PO week or All Star Week or maybe a week filled with hard games).
Similarly, it is also the NT coaches' choice whether any player will be chosen for the NT based on the pool of players that are made available to him or her (even if the manager follows 100% to the training proposed by the coach)
