You know why nobody is going to list that horeshit sport Pro Basketball? Because only about 10% of the players in the league give a consistant effort.
Sucks too because basketball (in general) is one of the most beatable sports when you factor in that so much of the game is based on %'s and #'s which makes the game easy to beat for those who are sharp enough to work w/ those #'s.
However... in the NBA (because of guaranteed contracts) you never know who's going to show up.
