Like Brett Favre, Tony Romo has made a name for himself as not only an extremely talented NFL quarterback, but also as a charismatic personality on the gridiron over the years.

On Tuesday, the entire football world was stunned as Romo, who was included in a number of trade rumors, retired and announced that he’d be joining CBS as a full-time NFL and golf analyst, alongside Jim Nantz, who is a longtime friend of his.

However, alluding to Favre, who Romo cited in the following quote, he isn’t going to completely close the door on a future comeback:

"I wish I could tell you unequivocally, 100 percent, for the rest of my life, I'll never play any sports at all," Romo said in a conference call to reporters on Tuesday. "I don't envision coming back. But I've also seen enough things, you know, from (coach Nick Saban's) 'I'm not going to Alabama' to (Brett Favre's) 'I'm done playing football,' that happen in life.”

A one-percent chance is still a chance. He went on to explain that he can’t envision himself stepping foot on a football field ever again and he knows that he will get calls now and then.

"Do I envision coming back and playing football? Absolutely not. I'm committed to CBS. I'm going to be there. ... I'm sure I will (get a call). There's not enough quarterbacks that can win 12 games in the NFL anyway. I do feel like, for me, the reality is a lot can happen. Right now, I'm telling you that I don't think it would be that hard of a decision.”

A lot can happen in a short amount of time.

Romo will be thrust right into the fire at CBS, where he will be part of the network’s top team of broadcasters. That is remarkable, considering that he has virtually no experience in the booth. But, it seems like he’s up for the challenge.

"I'm gonna get in the booth, I'm gonna like it. It'll be a challenge, but I'm excited. And I don't envision that really being something I'd have to think long and hard about," Romo said. "I'm just telling you it's about 99 percent and if, for some crazy reason, (CBS Sports Chairman) Sean (McManus) decided to fire me in Week 12, I guess I'd have to think about playing in a small golf tournament or flag football.”

Romo’s career with the Dallas Cowboys will likely be labeled as bittersweet. While he went 78-49 with 34,183 passing yards, 248 touchdowns and 117 interceptions with a lifetime 65.3 completion percentage in his regular season career, Romo went just 2-4 in the playoffs and failed to win a Super Bowl with “America’s Team”.

However, the fact that he turned himself into one of the league’s most prolific passers after signing as an undrafted free agent remains one of the most remarkable personal stories of perseverance and persistence in NFL history.

It will be interesting to see if he ever un-retires.
