Ideas for hanicaps...
1- Leave mine as it is. Hell. Even let vets force trades on me. I ask for an 8pm cutoff on opening night though so I can set my line-ups. I will let the rookies assign my ballpark.
2- Force a vet to have 10m available in the bank all season long.
3- Make the 11 other owners assign 1 player each to a vet team, and that vet has to keep those 11 players on their team all year. Not allowed to drop or trade them at all... ever.
4- Force a vet team to drop or trade their highest priced pitcher and hitter each time the FA penalty changes. 6 players total are "forced" from their team during the year.
Just some thoughts. I'm sure you could find 3 vets to take those propsed handicaps or even come up with their own.
