That guy is definitely a SG, not a SF, mostly because his crappy inside shot, mediocre inside D and 6'2" height. You'll still get the benefits of his rebounding at SG, so that's nice.
I would agree that spending the rest of the season on OD is a good idea. He'll need more OD next season, but you can also throw in passing, along with some 1 on 1 for HDL/DRV and some jump range.
