That link doesn't say there were two champions. It says two teams held trophies. I dont know if the AP actually gives you a trophy for being #1 in their rankings, but even if so it doesnt give you the championship. It does NOT say there were two champions. All the site is implying is that there was still controversy. The CHAMPIONSHIP game determines the champions. Your argument would be like saying that the Colts are a split champion this season even if they dont win the Superbowl but the press votes them still #1.
