Do we know that they have made offers to Arrieta and Darvish? The only person reporting that several trades are set up is HH19 so, again, you are making an assumption here. I'm guessing there are literally hundreds of reports of teams checking in on players and I'd even say it's likely that most teams check in on quite a few free agents, this isn't news. So yeah, in my opinion, this adds up to a whole lot of nothing.
