I don't know how I emotionally made it in 2014 and 2015. Imagine if the Chiefs had 3 more games this week.
I think because each baseball game in the playoffs is more like a drive of an overall football game it makes each individual baseball game less an emotional wreck. As long as you're not facing elimination in a game in baseball if you lose, it sucks but it's more like you let the other team score on that drive, so how are you then going to respond in the next one.
It's also why if you only have the one game (see 2014 wild card) it's rough ridin' high of highs and low of lows cause that's all you got.
