Cheaper, yes, but a better, faster trainer, most likely no.

Power train your token youngster and he will be on your team for at least 6 seasons, and most likely more.

If you build your practice facility, you can get 7 rests every 4 days, a rest as a gift each day and the rests for making subs during matches. So, if you use your rests wisely, you can power train a youth or two and keep them for a long time without spending another token on them.

If you buy older players, you have to replace them every season or two. If you spend 5 to 8 tokens per player every other season to win them at auction, you will wind up spending about the same amount of tokens over the long run.

Just something to think about...
