Jake thought it would certainly be a big nightmare if it were really like that in reality, playing with opponents who were better than him in almost every skill and knew how to use their skills better.
But it did a little to take away all the arrogance that Jake had being the first pick in the NBA draft and winning several individual awards at College basketball, Jake had to learn that even if he had good skills he would still start as an NBA rookie.
It was certainly difficult for other talented players to learn this lesson in humility as Jake learned before he even joined the NBA, but it would probably make teammates find him more enjoyable if he was humble in the beginning.
Of course, Jake still had the same dreams and still thought he wanted to win several NBA titles and be the MVP in several seasons, but he didn't need to think about getting it in his first NBA seasons.
