Ms Duff has a good point (she usually does).
I know the SPL very well. Lived in Glasgow for 4 years and watched many matches including old firms (8), internationals and cup finals (and semis). It is very Championship like. A lot of kicking players, sending offs, brawls etc.
Now I have to admit I don't know much about American players (but I am trying to learn and study up as I am here to stay)but if this gent is a tad tender, young, and doesn't have the physique, I'd say do not send him to the SPL. He'll get hammered up there.
French (or even Dutch) football would be better for him to develop.
