I agree with a lot of what has been said so far. In my opinion:
1. Gameplay has gotten stale/predictable.
2. No penalties for player overuse or play overuse that seem to have an impact
3. Injuries seem to be rare. I’ve played around 40 seasons...I think I’ve used IR twice. Takes away the realism that I think a lot of us want with total roster mgmt.
4. Too many leagues.
On this point, I think initially the game should give you access to one team for the first season. Learn how the game works. At the end of season 1, give them access to a second team. And then from there, either a winning record or playoff berth unlocks additional teams. And if an owner bails on a team in mid season, reduce their total team count by 1. We are diluted with leagues, making it easy for new owners to jump around if their initial team doesn’t play well. I’m sure there are 100s of flaws with this, but this is just an idea to work from.
5. Make adjustments to eliminate game exploits like punt block quickly. This can frustrate new owners who don’t know the override system and can’t understand how they gave up 4 blocks in a game. Too easy to frustrate them and cause them to move on.
I’m at 4 teams right now, and it’s a challenge to find time to game plan/draft prep for all of them consistently. I don’t know how the guys with 10 plus teams do it.
