Let me give you some immediate actions, then I will have a deeper look later.
a nice player. My Lisanti was weaker, same potential, a lot of satisfactions
Your priority is to bring him to 9 OD and 7 JR. I expect beside 8 HN/DR, may be 8 JS. If in this monorole training period you need a birole (and he's your primary trainee), do JS.
Knowing the goals for OD (PG spot) and JS (SG) allows you to flexibly arrange your team, as you need. Try planning at least two weeks in advance. These pops should take about 8-10 weeks, depending on decimals (183cm will help anyway).
Than we'll see.
