Dallas Cowboys almost did not get their star quarterback, Tony Romo.

Romo, who will mark the 2015 season as his 13th year with the Dallas team since he joined in 2003, per the NFL stats, wanted to initially join the Denver Broncos, The Dallas Morning News reported.

The Eastern Illinois University alumnus, shared on "Star Crossed" that he received calls from 20 teams, right after not being picked in the NFL 2002 Draft. Romo thought of three teams as his best choices, namely Arizona, Denver and Dallas. However, it was really the Broncos he was eyeing that time.

"I really liked Denver because of Coach Shanahan. I thought he was fantastic. I liked their system, all that stuff, but it also came down to who can I beat out? What team can I make?" Romo said.

Eventually, he became a Cowboy, as he thought the Dallas team need a quarterback more while he may not have his chance to shine or play much with the Denver since Jake Plummer was already the defined starter of the team.

Yet, what was interesting was how he thought of himself as a quarterback. The athlete did not even think he would be good enough to be in the NFL until his last stellar year at Eastern Illinois, where he was reportedly honored by a Walter Peyton Award. Romo even thought all those college popular quarterbacks during his time were "all better" than him.

"I always felt like I wasn't good enough technically and I knew that. When I went to a combine or a place and saw people throw, they were better than me. Now I was given just a gift from the Lord the ability to see and react quickly, so I had that on other people but I didn't have the ability, the just refinement to the game, the structure and fundamentals that you need to play at a high level. I did it on just natural raw ability and I needed to get better and I wasn't there yet. That's why I had to throw a football 360 days a year," the 35-year-old quarterback shared.

Now, he is a respected Cowboys quarterback and leader. Bucky Brooks of NFL.com commented in 2012 that what's impressive about Romo is his "poise, accuracy and ball placement under pressure." The San Diego-born football player had "repeatedly delivered pinpoint passes between multiple receivers for key conversions" or when they mattered most.

In his 12 seasons with the Cowboys, the recipient of the Nancy Lieberman Lifetime Achievement Award tallied his record-high of 4,903 passing yards in 2012. Last season, he posted 3,705 passing yards.
