I think there are at least six Sooners on the two Super Bowl rosters. SF has two. Trent Wiliams and Braden Willis.
Four Chiefs, although Blake Bell is on injured reserve I believe. But Mike Winchester, a longtime long snapper has the second longest longevity on the team behind Travis Kelce. Of course Creed Humphrey is a great center. And Wanya Morris doesn't start unless someone is hurt, but he's on the roster.
OU will be well represented.
