I think that JS 16 and JR 18 is really poor skillset, affecting player's salary a lot. I would always go for JS 18, JR 16. I meant to say that Driving = 11 and Handling = 7 is nothing compared to other, main skills for player of that level. Driving and Handling overall can't be useless.
To conclude, this player was great prospect in U21 but his other, very bad, skills and extreme salary made him a free agent.
