Orcin is right on the money IMO.

I would stress that you need to take a few risks sometimes.

Don't be afraid to pull the trigger on a trade....most guys can be replaced.

I would have a long term goal in mind when acquiring players. It's like chess always be 5 move ahead.

I.E. Even if you have a guy signed long term, but see a player in another teams system that's a possible replacement try to get him. You never know if he will come in handy later.
Another thing, I usually try to get throw ins on a trade. I'll find a utility player or a decent pitcher and ask for them. Sometimes I'll flip them, sometimes I'll keep them...either way they can prove to be handy.
