The Rays. It's not because I like them, it's because I don't like who they beat to get this far.
If the Rays win, Tampa will have a shot at winning 3 straight championships in different sports - hockey, baseball, football. Obviously I don't want the last one to happen, but I wonder if it's been done before. Closest I can come up with is Jets (1968/1969), Mets (1969) and Knicks (1969/1970).
