how did you decide that we are all compulsive gamblers? and how did you decide that we all don't know half the players in the league? Also i know the difference between your and you're, i am just not that worried about it since this is a gambling forum and I have to deal with members such as yourself who post crazy assumptions out of thin air.
there is not need to worry about players who rarely touch the court, if at all. if an injury arises then you can easily research that prior to tip off and adjust according. but if they have seen very little nba action, you can't strictly base their talent off past college success.
