Id train him up as a 'bigger' SF.
So start out basically training him in PF stats. IS + ID. These will train fastest cause of his height.
Don't worry too much about SB... and passing/handling can wait a little bit.
Then once you get your PF stats up a bit, around strong, id train driving. You will get some supplimentary pops in JS from training IS + DR, so don't waste your time training JS.
If you keep training the ID + IS once they get to a 'strong' level or thereabouts, his salary might start to blow out, - actually it will be higher than this, but anyways, you get the idea.
Then in a couple of years, you will need to top up his OD and Passing.. then voila! nice SF :) welll thats what i would do anyways, other people may disagree.
He is only listed as a point guard because of the way the calculation for position works. But just ignore that listing, it doesn't mean jack.
