Text to text connection

I have just started to read the book "Mracle on 49th Street" by Mike Lupica. So far, I can already find a text to text connection within the story. In this story, a girl named Molly goes to the Boston celtics training facility. She waits outside to meet one of the best players named Josh Cameron. She claims to be related to him some way. I connected this with the movie "Gameplan". It is pretty much the same story. A girl shows up at a famou football players house and claims to be his daughter. I don't know how this story will end, but so far it is looking very similar to "Gameplan".
