First of all, you've scouted him twice, is he B+, B or B-. Also, and most importantly, 18 or 19? If he's B+ and 18, absolutely the SF. If he's 19, then absolutely the C. Otherwise, if he's 18, but B or B-, you're taking a gamble on superstar vs. perennial allstar. If you plan on training this guy, and want to keep training that SG, I would go with the SF.
