I'm not against acquiring Bichette, but his defense at SS is pretty bad. He likely profiles as a 2B at this point and we already have several of those.
I'll let others on the list weigh in on whether Bichette's D is that bad that it would offset the improved offense he'd provide. ;)
The Nationals are supposedly open for business on young starter Mackenzie Gore and SS CJ Abrams. Both would fit on the Tigers IMO but Abrams D is also subpar. I imagine a theoretical deal for both of them would include the likes of Rainer, Briceno, and Melton at least, assuming that McGonigle and Clark would be off the table.
I agree Meadows could be part of a package deal (maybe a theoretical one like the proposal above), but I wouldn't mind keeping him as a 5th OF/defensive replacement. Maybe He comes into the game late and Baez moves to SS for defense in those situations.
As for acquiring a RF, are you proposing that Carpenter would then be a full time DH? What do you do with Vierling and Perez (not that they're that great but they presumably have to play somewhere if they're going to still be on the team)?
