I don't really agree with this. Yes, free agents sign with teams they want to play for, but they also sign where the money/contention window works out for them. Us signing Markakis last year and trading him now is different to, say, the Marlins firesale back in the day. What they did, signing a bunch of bigtime FAs then selling them all a year later, is different from signing a mid-tier FA, changing our contention strategy pretty significantly in the meantime, and then trading him. I don't think future free agents are going to look at us and say, "Hmmm they kept Markakis for 2 years/1.5 years instead of 1 year, I can sign there." If anything were to negatively impact us in future contract negotiations, I would actually say it's trading homegrown guys like Andrelton right after signing a long-term extension (though I also don't think it will matter much if at all, just a consideration).
