"The way he is now is night and day from last year," Thomas said Tuesday. "He has a bright future ahead of him."
Thomas quipped that Manziel, recently released from treatment, now spends his Saturdays studying the playbook and watching film instead of riding "a swan in a swimming pool drinking champagne," saying: "It's apparent he's realized how important football is to him. He's realized you can't get away with those things anymore."
Said Thomas: "As one of the leaders, it'll be my job to talk to him sometimes, (but) he's already impressed a lot of people here now in the last couple of weeks."
"He has the it-factor. He has what you can't teach," said Haden, adding: "Actions speak louder than words. He's putting forth those actions. That's all he can do."
