Biggest Mistakes

Here are some common mistakes made by new owners:

1. Signing mediocre players to long-term contracts. Especially a Type 1 for a player off the draft, as you will have to either renegotiate the contract to a Type 2 or 3 (recommended because of no release fee) for the ability to release the player who isn't playing up to what you thought they would. Another mistake is a Type 6 contract (long term from your Auxiliary Roster), as you have no option but to retain said player until the season is over.
2. Drafting a single-season player in the first round (in this sim you have to plan for the long haul). It is currently 2018, OF Aaron Judge just hit the draft pools. He has ONE season under his belt, albeit a great season, there is no discount on a single season contract. My advice on this is to try to draft said player lower in the draft rounds (maybe 8-20 on your draft card). Let's say you end up drafting a single season phenom like OF Aaron Judge and want to keep him on your roster for the coming season. You should consider a Type 3 contract, as Judge has the possibility of hitting quite a lot of HR for your team, thus doubling the income from those potential HR games and/or 40 HR season (or more, considering the size of your ballpark).
3. Calling up a highly-ranked Auxiliary player on a short-term contract.
4. Not monitoring the financial state of your franchise.
