It took a few minutes of perusing Richmond.com since Maxpreps is so inconsistent with stats. At SFA, JJ averaged about 150 attempts in 2 seasons as a starting QB. The QB for Henrico High last season averaged between 25-30 from what I could gather. It is a smart decision to transfer. He needs a ton of work when it comes to accuracy.
He threw 155 attempts at Henrico: from the article, "During his sophomore season, he completed 88 of 155 passes for 1,235 yards, 18 touchdowns and five interceptions." Which is around 15/game (if he played a 10 game season).
He only played 1 season at SFA. I think he only threw it 80 times last year.
In this article, his stats are very mediocre - because SFA dominated teams and rarely threw the ball. He had one game he was 2 for 2 for 18 yards passing. Can't blame him for transferring back. His coach is doing him no favors (but can't blame the coach, if you're winning big why throw the ball?):
