If we're concerned about the past records so much, and I'm not sure why, then the last three times our very own Toronto Blue Jays lost a game 1 in the playoff series, we went on to win Game 2. For the 1992 ALCS and WS we actually won three straight after that game 1 loss, which in a 5 game playoff situation would have won us the series right there.
If we lose tomorrow we have more reasons to panic, but not really on just one loss.
