Not sure I'm really understanding the 'don't sell low on Vlad' POV. He's two years from free agency. How likely is it that two years from now any of you are comfortable giving him a free agent contract? If it's more of the same the next couple of years he's easily replaceable and not a loss at all. If he's 2021 Vlad over the next couple of years, he's getting a mega-contract. But do you want to be the team giving a huge contract to a fat, inconsistent, bat-only 1B who bleeds runs on the bases and is already a bad 1B defender?
I think it's basically a choice between trading him now, or trading him in a year. And any uptick in value that comes from a performance improvement in 2024 will be at least partially offset by the fact that a year from now you're trading one year of control instead of two.
It's really close to decision time on Vlad.
