Yes if you get the fast trainers, nordgens or hot prospects are almost guarrantees, 5* are what most people go for if they can not afford scouts, but you can get 3/4 * hot prospects that will do a good job.
You don't have to break the bank getting Q4 or Q9 when Q3 or Q8 hot prospect fast trainers will do just aswell!, the main thing is getting young players.
