Mohd Al-Rifaie bin Mohd Fuad (15028408) Point Guard
he can/should be hard trained as either SG or (probably better) PG in long term. He has just a big problem in driving, the easiest skill to train (1v1 and as secondary), good JS/PA, and more than decent other skills, plus much appreciated IS and ID (training OD you will have one good pop somewhere in ID too).
he needs of course intensive monorole training, 48 minutes per week. Nothing less. Unfortunately his potential will cap him, but believe me, you can create a very good PG out of a star like him (my Lisanti was similar, some more driving, and he is a very good PG now, with some room to be completed before getting the cap)

I would definitely train him as secondary trainee after Fuad. In other words, you will arrange weekly monorole training to ensure 48' at least to Fuad, Jafaar will adapt. I would recommend you to train him as SG. His height will make him to grow a bit slowly, but it would be a nonsense to train him as C or PF, too bad to start.
be careful, Because of height you should start with OD/JR first, as with age+height they would become unsustainibly slow. Passing is not good, he will not be a great player, but at least you can make some good money by 2-3 seasons.
by the way, all that means that you should train monorole for all the season and most of next one, decreasing progressively in the other two. so you have additional room for a third trainee.
