Yay, he tore up the GCL, Short Season, A, A+, and had a good AA showing and what amounts to a fullish season at Norfolk (where he has had 1 good month.)
Good for him. He wouldn't be the first player to tear up the low minors then struggle.
And no, I'm not writing him off right now. But the things that were concerns in low ball (defensive) and upper minors (hitting) still appear. Even if he did change his approach and had success in Norfolk recently, there is still tweaking for the majors.
