Not necessarily.
To be clear, I wouldn't advise to have a player with this ID even in a PG-SG spot. However, not all the time we have the opportunity to play with a lineup close to our belief and, especially in div IV, having players capable of defending both ends it's not as important as in higher leagues.
I'd go pushing his training to give him some strenghts, knowing that ID is an area of weakness that in higher leagues you'll likely need to eliminate. Just pay attention that a potential 7 will have some cap limitations pretty early as a SG
