heyyyyy, i'm not THAT bad....
I threw 2 games at the beginning of the season, i played the top 2 teams on TIE, just for the added enthusiasm. I havent lost a game (league game) since then and i'm now 2nd instead of 3rd, I guess i may have been able to do it without throwing those games at the beginning but i can guarantee that throwing those games made this season a LOT easier for me, even allowing me to have enthusiasm levels of 9 etc for tv games, giving me bigger wins and overall more money.
I guess if you are coming 5th and want to play in the relegation games and get a better pick in the draft it may be worth tanking the last few games to become 7th or even 8th, but just make sure you can win the relegation games!
