Having watched baseball heavily for 30 years now I can say without a doubt, yes we can expect different results. Judging a player over a single season is dangerous, worrying about what they did over 3 starts is just silly. Teams that flip out and make big changes to the roster just because of playoff results tend to not fare very well the next season because they are going about the process completely the wrong way. There is no magic formula for winning the playoffs, get the right guys hot at the right time, stay healthy, maybe favor your bullpen a little extra.
