Sharma and Mooney put out a podcast this morning. Most of it was kind of commiserating about how boring the winter meetings were. But they did address this report and it was kind of fascinating. I loosely transcribed what Mooney said
"We don't write every single thing we hear. There's lots of stuff that ends up on the cutting room floor. In order for us to write something it has to clear a pretty high bar in terms of who we're hearing it from, where we're hearing it, and how frequently we're hearing it. And the Nico rumor cleared that."
They bookended it by saying the team loves him, he's probably not going anywhere, etc. But I thought that was a notable bit of throat clearing.
My guess is that the Cubs are not shopping him but that there is a team or two that is pretty seriously trying to make a run at Nico.
