I don't know, it is a long season. You can't freak out every time you lose, sometimes things just don't go your way. Blowout losses have always been easier for me to handle as a player than the close ones. The close ones haunt you over a play or two. In a blowout you learn pretty early that the game is decided, and so you move on mentally.
Playoffs would arguably be different because you are really limited in the amount of games. It is healthy to be able to put a bad game behind you though.
