Jake's friends were surprised to hear his ambitions to play in the NBA in the future, they didn't remember seeing Jake being ambitious and talking so confidently about his dreams in the future.
In fact, they thought Jake was even too humble for someone as talented as he was, it was normal for talented people to be arrogant and say what they really wanted at times, but at university Jake always talked more about the team than his skill.
But hearing Jake say that they realized that he always knew the talent he had and in fact always thought about becoming an NBA star, they thought that Jake should stay at the university to break individual records at the university because Jake was close to achieving that.
