Not necessarily. Statistics show that since the 1970 merger of the NFL and the AFL there have been 20 instances of a team from the opposite conference winning the Superbowl as opposed to the conference team that won the Pro Bowl in the same year. There have been 19 instances of a team from the same conference as the Pro Bowl winner , winning the Superbowl in the same year. This makes it almost dead even. Since 2000 there have been only 4 times that a team from from the opposite conference as the Pro Bowl winner, has gone on to win the Superbowl.
