As i said, you should know the history of the team that drafted you out of respect to the guys who paved the way for you to have a career at the very least. You wouldn't go to a job interview without knowing a little history about the company you are applying to would you?
Are they about to enter a professional sports league? If so then they should know about the team who they are playing for atleast. I don't know any pro doesn't have respect for the guys before them and the history of the game, its why they play.
