Rules suggestions for franchise mode?

Starting up a franchise mode in the near future and am trying to make it as realistic and challenging as possible. Here are some of the rules/restrictions I have come up with for myself. Can you guys help me add some I am not thinking of?

  1. ⁠⁠Must stay under the coaching/scouting budget. Will be using owner mode, but set to auto.
  2. ⁠⁠If I sign a good player in FA, thinking 85+ OVR, I must keep them for at least 50% of their contract. A one-year player may be moved at the deadline if I am not contending, odd years must play the full season after 50% (ex. 3 year contract may be moved after two full seasons.)
  3. ⁠⁠Trades must be realistic. I may not go out and grab Connor McDavid for example. Trades need to make sense for the opposing team. If they have 3 first/second line centers, they will not want my 86 OVR pure center for two seconds.
  4. ⁠⁠When signing players, I must try to keep the contracts fair. A 20 year old sniper who is looking to become a 50g/100p player will not be willing to accept 3mx8y. I either have to give them a bridge deal or if I want 8 years, it has to be somewhere near market value(with a slight potential discount for the length).
  5. ⁠⁠If I am rebuilding, I must try to keep the team somewhat competitive. I cannot ice a team of AHLers to tank. NMC needs to be respected and treated as a FA signing(50% of contract rule).
  6. ⁠⁠I am only allowed to use auto-scouting and all of my scouts must be C or lower.
  7. ⁠⁠I may not move up to a draft spot unless the team wants to move the pick. This applies to teams who are most likely going to finish bottom 10 next season.

These are the ones I 100% want to use so far. I have a few others I am torn on.

—-Should I have a limit on how many players I can give off-season training to or how many player goals I can give? Should it be only for prospects or a certain overall?

—-Should I have a draft pick limit per year? Should I for example only be allowed let’s say 3 firsts max in a year/ 10 picks per draft?

—-Should I have a rule for my lines regarding player role? Such as a first liner can only play on the first or second line?

—-Do I have to respect the interest in resigning yes/no? Should I have to respect it for UFAs but not RFAs?

—-What else can you guys suggest? Thanks!
