All of those trainees a´have their weaknesses.
The second and third one are quite tall and it will take a long time to bring them up to decent second league stats.
It depends on what you want to make out of them: PG or SG.
For PGs: Passing and OD are primarily needed, thereafter JS/ JR.
For SGs: JS/ JR and OD, thereafter passing. Well, and free throws are very low as well. So, to be honest, it´ll take a long, long time to turn all of them into decent players.
At least the third one is more of a PF/ SF guy. He can be trained to a solid PF at least. There he would need some more JS/ JR and OD apart from the inside skills.
