Yes there is a setting that says "After draft make all players:" And you can choose FA or Waivers. FA will allow teams to pick up players freely. But the players they drop will also become immediately available. They could be throwing out the baby with the bathwater.
Sorry to thread jack but, I can't change the waivers to FA. I want everyone to pick up and drop players until regular season starts. The setting "after draft make all players" say follow waiver rules, I set waiver rules to none and yet the players are still on waivers..... any ideas?
