DALLAS (105.3 THE FAN) — Johnny Manziel has yet to accomplish anything at the NFL level. Emmitt Smith accomplished plenty.

The former Dallas Cowboys and Hall of Fame running back was asked his opinion of Manziel’s perceived lifestyle. What would he tell the rookie QB?

“First, let’s recognize — Johnny is young. I was young and dumb myself at one point in time,” said Smith to Shan & RJ on 105.3 The Fan. “But maturity itself, and maturing as a professional athlete, is something that is required of every pro football player. I think right now Johnny Manziel is going to get a glimpse of what negative press can do for you. A lot of people think negative press is good press — or any press is good press. It’s not.”

Fair or not, images have surfaced on social media of Manziel partying in Vegas, drinking from champagne bottles at bars, and using a stack of money as a phone.

Smith says that Manziel will ultimately have a decision to make: how can he maximize his true potential in every aspect of his life?

“That’s on the field, off the football field, having the power to influence others at the same time in a positive direction,” said Smith. “That only takes time and it takes maturity.”
