In 1980, what two notable quarterbacks, who had both started multiple conference championship games, were traded for each other?
Dan Pastorini and Ken Stabler. Pastorini was coming off a pair of AFC Championship game losses against the Steelers. Stabler at one point played in five consecutive conference championship games with the Raiders. So they made the big trade (with neither guy having much success with his new team). Those two teams will play on Sunday, though both are now in new cities (the Houston Oilers becoming the Tennessee Titans, and the Raiders now in Las Vegas).
