Here is MFL's response to Pat's question:
"Yes, see below for general guidance on this. We generally make position changes in the off-season about once a month based on anticipated formations for each NFL team. The last set of changes will be sometime in August, after which point you would have to manually change any players that you need or want to change for your league.

Thanks

This question is answered in our Help Center, which you can access from the "Help > Help Center" menu, in the "Players & Lineups" > "NFL Players" subcategory:

Why is a player listed at the wrong position? Or, what happens if a player changes the position he plays during the season?

Player positions are updated periodically during the preseason from the depth charts at FantasySharks.com. Once the regular season starts, we no longer make player position changes. Your league commissioner can change a player's position if needed by using the For Commissioners > Setup > Players and Rosters > Change Player Position option.

You can review the player position changes that have been made during the preseason on the "Help > What's New" menu item under the Player Position Changes link."

So I think we roll with it until the season starts? Not really sure what else we can do. Most of us seems to have been affected by this. Maybe new rules that if MFL changes player position in same off season as player was acquired, can cut said player free of charge?
