If you are bad at FA and trading it means that you have incompetent people making those decisions.
If you can't make trades and are not aware of what the options are, it is because you have part time GMs who are more interested in putting on concerts and other events at the stadium
The answer is not to completely sit out of these options, it is to hire full time competent whose full time job is ONLY AND ONLY to make the team better
Will never happen with moron and sons owning this franchise unfortunately
But remember "Jerry is a great owner"
