Tony Romo insists his NFL career as a player is over. Romo broadcast his first regular-season NFL game when the Raiders played the Titans on Sunday, receiving an A grade from SportsDay media columnist Barry Horn and praise across the internet. He says he's not going back to the field. But does he regret not making a Super Bowl?

Romo discussed that and more in a recent interview with Sports Illustrated/the MMQB's Kalyn Kahler.

"Oh yeah. I mean sometimes you can win a Super Bowl and not play very good at the quarterback position," Romo told Kahler. "You can be part of a team with the No. 1 defense or you can be part of a top-five team, and sometimes you have to be perfect to win every game you play. It just depends on the team you have and the season you're in. It is obviously a hole on my resumé, but we don't get to choose when we come about and what time. We all wish we played for the '92 Cowboys. Or you wish you had the No. 1 defense in the league, the '85 Bears. That would have made it a whole lot easier. Peyton Manning had a No. 1 defense and he wasn't even playing at a level like he did his whole career, but when he had that in Denver, they won a Super Bowl.

"At the end of the day, you work your butt off and you have to be able to sleep at night knowing that you gave everything you possibly could. I feel like I can sleep at night knowing that I may have come up short, but I gave everything I possibly could and playing for this organization was a dream come true for me. That's a special feeling to have that. I just feel like I was one of the lucky ones."

Here are more highlights from their interview:

On taking notes for broadcasts: I would say, first off, that my penmanship isn't very good, so you won't be able to read it. You'll be disappointed in that, I probably should have done that better in grade school. I use a highlighter, I do like that. ... But I don't have any trade secrets yet. I'll learn them along the way.

On the Cowboys' spotlight: Not every team has the following the Dallas Cowboys have. There are positives and negatives. Whenever you play poorly it is going to be talked about ad nauseum, more so than maybe other organizations. But at the same time, if you played well, you'll almost be put up on a bigger pedestal. I think that all the quarterbacks go through that in Dallas.

On his concession speech to Dak Prescott: I spent some time thinking about it and coming up with it, I wrote it out. I started the process the two days before. I sat down and just thought about what I wanted to say and how I was going to do it. Then the night before, I just spent all night coming up with what I wanted to say, it was from the heart.
