optimizing team policies for 1 single player and optimizing team policies for the entire squad rarely coincide
To make it short: speeding up training would sure make the market full of the top players we see once or twice nowadays. But they wouldn't be top players anymore, and the top players would still leave for enormous amounts of money.Speeding up the training would only elevate the quality of players, it wouldn't regulate supply and demand.
Why are you so sure 21 year olds are also up for this? It's U21, isn't it? It don't know either, but doesn't that mean 20 is the limit?
so here the answer .. the junior NTs will be U21 .. look NT Rankings ..and it's inclusive age 21..what you says ..
