Small things JDB could have done to make MFN more playable right now that would be easy.
1. Add the ability to enforce weight and position restrictions at positions. Leagues don't have to have rules that way or the rules are programmatically enforced.
2. Allow offensive and defensive rules to select plays and not play types for situational game planning.
3. Remove the drop pass nerf.
4. Reduce the effectiveness of B&R for down field coverage.
5. Make OL hold blocks longer than .5 seconds on medium and long passes.
