I sent those numbers to a friend who is very down on JG. He checked and says that the numbers are incorrect. He says JG is actually 12-17. I'm not gonna invest the time to check those numbers either, but I would not be surprised if he is right (information on the internet is very often inaccurate - bon Jour). The 12-17 is still not good, but it would at least be better than 9-17.
According to this friend, JG is 18-20 in games that he has played in and 6-3 when coming off the bench.
I'd buy that for a dollar
Don't have time nor really care to investigate myself
His current level of play (or lack of) is enough for me
