Hard to say what was "better" 1984, or 1998. But for my money 1998 was harder fought. 1984 we came back from a huge deficit, but the Cubs are talented playoff losers. Garvey is a Dodger and general ass of a person involved in financial scams and being one step removed from a con-artist.
The 1998 Padres had to defeat a Randy Johnson lead Astros team, and dispatch the Braves in their prime (though they themselves were a special type of playoff choker).
I remember watching these games so intently, and loving how Sterling Hitchcock dismantled everyone.
