HAL* is omniscient, and peace be upon Him.
It's just a reference to superstition, forged in the furnace of humility over ten years of watching people post links to teams before a season ends that say things like "My awesome team is 50-20, do you think I'll win 125 games?" and then watching them finish 79-83 once HAL is finished destroying them. This is the reason now you see so few threads that begin with "My Awesome Team Is..."
Related topics include the following conspiracy theories: the wildcard always beats the winner from the same division, the game engine stats governor (or equalizer or whatever we used to call it) will stop you from winning 100 games, 100 win teams always lose in the semis, etc etc etc.
To wit, no TSF team (ie, the one declared as my annual TSF team) has ever won a ring. The closest I came was a game 7 finals loss. If you post your team before the season ends, you must confront HAL and HAL always wins.
(* For noobs, HAL is the unofficial name of the SOM game engine and is a play on HAL from 2001 Space Odyssey and Hal Richman, the game's inventor).
