To have scored 12 goals so far this season for the lowest scoring team in the Division marks him out as very high Championship standard. Agree its impossible to say how good he will get and I think the age thing is a red herring as well but give him some obvious credit, he is way above Div 1 standard.
Not sure in the logic there bearing in mind it is the duty of our attacking players to score more goals. If they had we wouldn't be a low scoring team and he and CMS would have just broken into double figures at this stage of the season!!!
