Despite competing for the same starting job, Williams and Rypien were so supportive of each other that T-shirts were sold with the caption “United We Stand", depicting the two quarterbacks as cartoon characters with Williams saying “I'm for Mark” and Rypien saying “I'm for Doug”. Williams would play one final season in 1989, as Rypien's backup, during the latter's first Pro Bowl season.
