San Francisco didn't actually take the offer, but told Carolina they will consider it unless someone beats them. This is all smoke obviously until a real reporter verifies it. The rumor also says that Carolina is moving up for Fournette, which echoes similar reports from Rappaport and Rotoworld that Carolina is 100% sold on Fournette and won't let him fall past 8.
I had Carolina trading up based on Rappaport's scoop. But I had them giving up less. The market for Fournette is steep if this is true.
