A source I trust tells me that USC is recruiting Chris Olave still but that it's not overly aggressive at this point. While he's still a target and could still possibly visit the school, the Trojans are prioritizing Devon Williams over Olave for the second receiver spot at this point.
Based on what I was told, I would be surprised if Olave ends up in USC's class unless the Trojans decide he's a priority and make up a lot of ground late.
