Train youngsters fast with the the specific training (rather than team). Will mean you get better individuals faster to either help your team on the court...or financially by selling.
For scrimmages just go through the "countries" area and pick various countries....those online will be shown, and those still available for scrimmages will be shown. Just invite as many as you want...you'll get one. The early part of the season may be harder with the Thursday scrimmage time taken up with Cup games, but it gets easier.
