In 1967, the NFL adopted the "Slingshot" goalpost, with a single post curving to support the crossbar. The NCAA later adopted the same rule, but later allowed the use of "offset" goalposts, with two posts rather than one. Three schools in Division I-A currently use two posts instead of one for goalposts in their stadiums. Washington State (pictured) is one of them, can you name the other two?
