I think some of the teams mean well, but are not sure what does and doesn't go on the schedule. Perhaps if MaxPreps would send out some guidelines, i.e., don't post Spring games, or Kickoff classics on the schedule, it might cut down on on some of the erroneous information. Maybe the AD needs to sign off on the schedule too.
I understand that this will not fix all of the ills, but it might be a good start
