Be warned, training ID will be a very slow and painful process because he's short and already 24 years old. Those 2 pops might take all season.
Personally, I'd give him maybe 1 pop of ID and then move onto passing. Passing is significantly more important than JR IMO. Even players with high JR don't make very many 3's but it adds a lot of salary to the player.
Still, he's a very nice player.
