go to BYU. He would/could be a legend at BYU, at Duke he will most likely be a role player. Both offer good to great educations, but one puts you with like minded people and continuing to study the gospel. Your chances of falling in love with a good Mormon girl are 100 times higher at BYU than at Duke. Could you find it at Duke? Of course, but your pickings would be slim. Much higher likelihood that the girl who is all over you who you think is good looking is not a Mormon.
