The first couple products of the youth academy are pretty useless. They get better as you upgrade the facility, though. I have tried keeping some of the free ones that were generated on my lvl 5 team, I will see how that goes. But they are very slow trainers, which makes them bench fodder or $ generation for the most part. If you have a lot of tokens to power train with, the token youth is usually a good player. But on the other hand if you have a server where you can buy gens for a few tokens, that's better, I think.
