Because all of these insiders that I can think of have at one point said it's a done deal. They may have retracted that statement, or provided storylines that excuse their inaccuracies, but so far nobody has really been validated, so I think skepticism is the smartest route to take. What do you have to lose by being skeptical about this? If BYU gets in, you'll wake up one day with a very pleasant surprise. That beats getting all worked up and excited over tweets by GSwaim and "Tuxedo Yoda" only to be disappointed once again.
