But he admits he might be part of the magic potion needed for the Cowboys to save their season and live out their Super Bowl dreams.
Romo has missed the past three games with a broken right pinkie. He threw and took snaps in practice Wednesday and is expected to return for the Nov. 16 game against the Redskins after this week's bye.
The Cowboys have lost two of their three games without Romo and have fallen to 5-4, last in the NFC East. Dallas, a team that won the East with a 13-3 record last year and opened the season as the Super Bowl front-runner, would be sitting home if the playoffs started today.
"This is a football team and no one player wins or loses football games," Romo said. "But any time you play the game you like to think you have a chance to help your football team. I just know I am excited to get back out there. I am excited to help this football team. I think this football team's best football is ahead of it and we'll be able to show that."
Romo is confident partly because his finger is getting stronger, and he is feeling healthy again.
It is not yet 100 percent, and it is still understandably painful. But throwing with a smaller cast, Romo can grip the ball and throw it effectively down the field. He can take snaps from center and from the shotgun.
"What can't I do? I don't know," Romo said. "I'd like to think going into the game it won't be too much. I don't want to put our team in a position that would be negative so I like to think that I am going to be playing at a decent level.
"We don't have the same splint on that we had that time. It's different. It's definitely I can grip the ball much better than I did at that time and part of that is just because it has healed a bit since then."
The Cowboys' offense has struggled considerably in his absence, dropping off in points and yards per game and increasing in sacks and interceptions.
Perhaps no one is more excited about Romo's return than receiver Terrell Owens, who caught just 12 passes for 100 yards and one touchdown in the three games that Romo missed.
"I don't think it's a matter of him coming in and trying to be Superman and really saving this team," Owens said. "But he's a very key part of this offense. With him back there, obviously we've had success with him back there. His record kind of speaks for itself. I don't think he has to come out and do anything extra special coming back from that type of injury. For him, it's just to come out and put the ball in playmakers' hands and let those guys make the plays."
Still the Cowboys know it's going to take more than Romo's return to save the season.
If truth be told, they were struggling before Romo was injured, losing two of three games after starting 3-0.
Romo, however, said he has learned a few things while sitting and watching and predicts the Cowboys are on the verge of a breakthrough and a happy ending.
"I know I feel very confidently about this football team," Romo said. "I know that I'm very excited about the challenge presented in front of us. I think it is going to be very enjoyable going out here and playing this game and going forward.
"I kind of got a sense of why we weren't doing certain things well or not, and I feel very confident in our ability to play well from here on."
