No need for him to post his plays. He share his analysis and opinions. Why post plays for people that don't want to take the time, effort, hard work, advice, etc to get better and handicap the right way, i'll say that goes for 97% of the forum. The same 97% of the forum rather just view people threads who just post picks and not know if that people really has any knowledge to the sport or what they're doing.
Because he use to do it and seems like he wants to. He doesn't have to give his exact picks, he can just post his analysis on the games, which is what he does in a lot of peoples threads anyway.
