I like the way you think... But, i started with superstar player
(25208949) and trained him till he got 21 yo (55k wage).He won me promotion. Then i slod him, got money in arena and draft. Got one player from TL, one Hof, Mvp , new (better) roster... Hof is now 21 yo. One of the best in generation. Im just w8-ing for next season to try and promote...
For scouting... Just plan it well, if you want best of the best, you have to invest... If you plan to get one, best way is to get 5k/10k per week, but you will have to w8 2 seasons at lesat and plan your position in league...
I personaly prefer to tain 2 players or just one, so i can add tainring to the rest of the team...
