Why are you concerned with what his overall rating would be? Tendencies and individual ratings would be the main factor in his playing style and effectiveness.
His overall would probably end up somewhere around 90.
I made a CAP and gave him these ratings based on his stats that season.

Sim a season with those attributes and see what kind of numbers he gets.
