"On the field, he and I would be very similar," he said. "I’m as competitive as he is, but he’s a nice kid too. Off the field, he’s you know, lived the higher life."
Staubach was already married with three children when he began his NFL career, so there wasn’t much of a chance to party like Manziel.
"By the time I joined the Cowboys, I obviously had a family and everything and Johnny’s still having a good time," he said.
During the filming of the commericial, Staubach took the opportunity to give Manziel some advice.
"I told him on the field the thing is your teammates have to have confidence in you," he said. "And I said the most important thing you can do is make sure transfer your confidence to them because if they don’t have confidence in you, you’re not going to get the job done.
"Johnny works hard and I think off the field he has a good time but it can’t diminish the feelings his teammates have for him as far as trying to win a football game. That’s about the only thing I really talked to him about a little bit. I don’t know if he listened or not but other than that we just had a good time doing the commercial."
