Poker Boggles the mind, how players can be this bad

I don't know how they can be this bad, and have the C.L. I see It time and time again. Yet time and time again, they end up having a meltdown near ITM. So there's 2 aspects I don't get.

A) How they make It this far, time and time again, and usually have a nice stack come this time of the game.

B) How do they end up punting It away later on, sometimes prior to ITM or prior to the FT. I mean It's near Impossible to punt It away when you're top 10 with ITM lurking like 50 spots away. Yet I see It happen
