In BB you need normally 2-3 trainings to get a pop in the main Skill you are training, and also train some skill secondary with a slower speed.
I just see you already bought some young player, and the linked guy is one of your older player with a low salary for ya team. But on none training position you don't need that young player, and i would concentrate on training guards or centers.
And I wont get good players at the draft.
don't give up the draft to early, i normally get one usefull player out of it ;)
