I suggest that you have a league restart. Everything be reset to opening day.
You find more dedicated GMs not ones who join to let a friend rape the team.
You have a trade council consisting of people who have great OOTP league experience *~COUGH ME COUGH~* so that we can get more organized.
LETS GET MORE ORGANIZED PERIOD!
Get one person to run the league i did a sim to help out but then i didn't know who to pass the file back to because we had no real commish
thats just a couple suggestions i see
