He sounds like a great candidate to be a SF or a PF. With A+ grade he will have very good starting skills, and because his current position is SG, that means he's likely to have good JS and JR. But with 4 AST and 3 steals, he probably has ok other guard skills.
How many minutes did he play. The 2 PF isn't too scary, but if he only played 20 or so minutes, then he has poor starting stamina, and might be foul prone.
With 4 ball potential he is like to be somewhere between perennial all-star and maybe MVP.
If he's a high potential guy, you could probably sell him for a lot of money (1 million plus, depending on exact skill breakdown). If not, sounds like a great guy to train and build a club around.
Nice find!
