tom i want to play qb but no one ever gets back to me when i post on the free agent list what should i do

your feet until someone lets you play

unfortunately you have to wait until next season. League rules have the rosters locking after week 3. So a team shouldn`t pick you up.
Sorry next season

best thing for you to do is start your own team!! Should that not pan out, look at the records of the weakass teams and contact them directly.
