I wouldn't think so. Andrus was bad in 2020, but it was 2020 so one has to throw out performance to some extent. Unless Texas sent some dollars with Andrus, the A's are committing to $28.5 MM ($14.25 for 21 and $14.25 for 22), which doesn't strike me as a team in sell mode. Andrus' performance has ticked downward after solid seasons in 2016 and 2017, so maybe that's the same trend that hits a lot of guys in their early-30s. But my guess is he'll be able to perform well enough to warrant the deal.
On a side note, it's difficult to believe that it will be 14 years at the coming trade deadline that we traded Andrus in the Teixeira trade and Andrus is the last guy standing (Neftali Feliz is a non-roster invite with the Phillies). That day is a day that will live in infamy on the old Scout board. Gnashing to teeth and rending of garments. I was anti-trade at the time, but looking back, I didn't realize how good Teixeira was. The bonehead move by the front office then helmed by Mr. Suspenders was not signing him to an extension before making the deal.
