If this were true it would be malpractice. Zero percent chance this is the case.
That said, it would also be malpractice to say anything else at this point.
Or we can take the man at his word and see what happens.
(You'll notice he didn't say they weren't having internal discussions on how to extend Devers or Xander.)
Devers is under control for two years. I'm not sure why you trade him now. They have a good core for 2023, lots of financial flexibility to sign FAs, trading chips aplenty, and some players on the way up (Casas in particular for position players, but pitchers in plenty - Winckowski, Bello, Seabold, German, Mata, Murphy, Groome.)
I mean, I honestly don't get the whole "Trade Devers Now" stuff that's floating around here. It might make sense in a roto-ball vacuum - but we're not in a vacuum. You have to look at the roster and think about this year, and next year. And the year after. Devers will be the lineup anchor for 2023, and maybe all of 2024, assuming there's no extension and the team is competitive. The team will in some ways be built around him. It makes zero sense to trade away his bat and defense to just go to the FA well and pay for such, or go to the prospect well and trade for such.*
If the Sox do go into fire-sale mode this year there are a handful of other guys who are FAs at the end of the season. (Plus they don't have to staple any dead-weight contract money to any other player in a trade, or make outrageous demands, so they can likely be effective if they go that route - just ask Heath Hembree and Brandon Workman.)
Xander may opt out, but he also has a no-trade clause. Who knows what representations he's made to the team? He's clearly still playing hard and is one of the more senior presences on the club, as well as being one of their few key bats.
Maybe they take offers for Xander if the team absolutely craters this week, or suffers a season changing spate of injuries somehow. But absent that, maybe they plan to compete for the WC even if they have a rough week - and if so, they're simply not going to be able to do that without Xander. Or maybe they have a plan to make a push for him this off-season, before he's a FA? Who knows?
*(The one exception to this generally would be lateraling Devers for a Devers-like talent with more control. . .but what specific club is going to make that trade this year given the current standings? I mean, there might be one. But there's a greater chance no teams fit that criteria or would be willing to do a deal if they did.)
