Unless Ashley is trying recreate the Kevin Jones spectacle of a few years back, i really don't think he'd silently commit to USC and come out and tell the recruiting sources that Ohio State is his leader. I recall that everybody assumed that Ashley was going to USC because he marveled over a trip to their camp over the summer. But since then, the USC talk has steadily diminished and he came out and made
OSU his new leader. I personally would be shocked if he was still a silent commit to USC.
Remember, players have historically committed silently on recruiting trips but then retract that commitment the second they get home. (Dwayne Jarrett ring a bell?) Maybe Ashley hinted at a commitment when he visited USC over the summer but feels a lot differently about things now.
