Well, that's impossible actually... because the pro bowl teams are made of of players from many different NFL teams. The best individual players from the AFC teams and the NFC teams are voted in, and they comprise an AFC and an NFC team which play in that Pro Bowl only. In the Super Bowl, the actual NFL teams who played the games throughout the season and beat the other playoff teams play each other. For instance, in any given year, one individual player from the Denver Broncos might play in the Pro Bowl because he was voted the best in his division. However, even though he plays in the Pro Bowl with other non-Broncos players, his team (the Broncos) won't go to the Super Bowl unless they beat all the other teams throughout the season.
