I was offered Addison Russell for Jose Fernandez in a 20 team keeper league. Russell is $0 and Fernandez is $1, so I'm not too concerned about their salaries. The salary cap is $70 and contracts increase $1 every year if a minimum AB or appearance threshold is met.
I have a team I expect to make the playoffs and perhaps compete for a title this year if things break right. Fernandez looks to me like a future stud with nasty stuff, but I don't think he'll be able to help me this year as he will probably be shut down by the time our league playoffs commence.
I've always generally operated under the assumption that I can find pitching fairly easily, and that it is hitting that is the scarce commodity. Do I roll the dice on the SS with upside or keep the potentially elite pitcher?
