ATLANTA - Claiming a miscommunication, Michael Vick abruptly changed his plea to "guilty" on charges of animal cruelty. "I just didn't realize what dogs they were talking about. Now that I've read the charges against me, I'm ready to change my plea." Looking at a jail sentence and a felony on his record, Vick has instructed his agents to begin negotiations with both Dallas and Oakland for his return to pro football in 2010.
