You, and others belonging to the CougarBoard "gullible brigade" latched on to any and all speculation to create a reality that never existed.

There is no evidence, whatsoever, that BYU was in serious consideration or negotiations to join the BIG 12. NONE.
When you combine little morsels of speculation, along with a pretty gullible and hopeful community of pollyannas, you get posts like this.
