Having posted a really long list the first time this question was asked on another thread, I'll just do this very short list:
Three Superbowl Winning Quarterbacks and MVP's
John Elway, Denver Broncos; Mark Riepen, Washington Redskins; and Jim Plunkett, whereever the Raiders were that year.
David Schwimmer from Friends, Matthew McCongnehey (sp?), Drew Carey and Will Ferrell from SNL are Delts.
You can see the whole list at
