I understand what Coppy said about Aybar is nonsense, just as it was when he said Aybar was a big part of the Simmons trade originally. Aybar makes 8.5 million and has had declining range numbers along with having a negative DRS for the last three years (-7, -3, and -3 again over that span). Now that isn't terrible, it's just no better than average and combined with his contract and coming off a bad season on offense I cannot see him bringing much value back in a trade. However, it is possible that he might be rated higher than overall market value by a team like the Cardinals for a few reasons. The most obvious being their current need due to injury and also because they might just like Aybar as a player. They reportedly tried trading for him a time or two in the past and at least once almost got him in a deal. So unless they feel he is in decline or that the asking price is too much, I could still see a match here. Then again, they also could likely get someone at the end of Spring Training rather cheaply that would suffice for a few months. Personally, I'd do that if I were them but from a Braves perspective I'd want them to overpay for Aybar.
That said, I could see us getting more back in a trade if we payed part of what he is owed this year.
