Heidi Russo has watched her son from the stands, half of her desperately wanting to rise and wave her arms with excitement in hopes that Colin Kaepernick might finally recognize her. She dreams, after all these years, that there might finally be a connection with the young man she once gave up for adoption.

"Then the other half of me calms me down and I just sit there and cheer like the rest of the people," said Russo, a 44-year-old registered nurse who lives in a suburb of Denver and went to see Kaepernick play in-person for the first time in 2010 when his University of Nevada team played at Colorado State. "I kept looking at him, thinking our eyes might meet. He might finally see me. I kept thinking it happened, but he never came to see me after the game."

For all of Russo's joy in watching Kaepernick, who has made a dramatic rise to starting quarterback of the San Francisco 49ers, there is an obvious sense of regret that he hasn't been a regular part of her life.

"I watch him now and I see how happy he is and I'm thrilled for him," said Russo, who said "I have to respect" his decision not to meet.

Yet she holds on to hope. "You can see that everything he wants and everything he has worked for is coming together," she said. "That's something that any parent would be happy to see for their child."

Russo has a Twitter account in which her profile notes that she has "a very special place in my heart for Colin Kaepernick." She said Kaepernick, who through his agent declined to be interviewed for this story, has exchanged a few messages with her, but that most of her tweets over the years have gone unreturned. Kaepernick's adoptive parents, Rick and Teresa, have said in the past they are supportive of whatever he wants to do. At the same time, Colin, Rick and Teresa have always been uncomfortable with the term "adoptive" parents.

"His parents are truly wonderful people," said Denver Broncos tight end Virgil Green, a teammate and roommate of Kaepernick's at Nevada. "I've been out to dinner with them and you can see the job they did raising him. I think he would view it as almost treasonous to them to meet with his biological mother or father. They did such a great job giving him everything he needed to be successful in life."

Russo admits that Kaepernick might have had a harder time becoming successful if she had kept him.

"I know I couldn't have given Colin everything he needed growing up," Russo said. "But I ask myself a lot of the time, 'Would loving him have been enough?' "

Russo was single and pregnant with Colin at 18, and a mother by 19. Along the way, she made the difficult decision to give up her first son (she also has an 8-year-old son). There was nothing easy about it. Russo said she initially interviewed three sets of prospective parents who were interested in adopting Colin. None were good enough, least of all the couple that "wanted to put him in the theater and have him play piano," she said. "He wasn't going to be in the theater."

Like Kaepernick, Russo was an athlete. She's 6 feet tall and played volleyball, basketball and track in high school. She was strong-willed and independent. Through the first eight months of the pregnancy, Russo had decided to keep him. Then, a family friend who worked for the Lutheran Social Services in Wisconsin introduced her to the Kaepernicks, who Russo said had two children of their own already, but had lost two other children to heart defects.
