I have no problem with the team signing Correa to a 7, 8 or 9 year, big $$$ contract. There have been other big-bodied SS who have stuck at SS and stayed productive into their mid-30's. The rest of the team will be young and affordable for the foreseeable future, Buxton is the only guaranteed contract after this coming season (not sure how Dobnak's contract works, maybe he's our Bobby Bonilla until the $1 mm buyout after the 2025 season). That being said, the onus then falls on player development, this up-coming core group needs to be better than the current core group (Kepler, Sano, Polanco, Buxton, etc...).
Gray, Mahle and Maeda will need to be replaced by SWR, Varland, Winder, Balazovic and maybe Canterino and Henriquez. I would rather watch these guys struggle and develop than watch the scrap-heap hopefuls fail like has happened the last couple of seasons.
Polanco, Kepler, and this years open spots will need to be replaced by Lewis, Julien, Martin, Wallner, Larnach, Kirilloff and eventually Lee, Miller and Rodriguez amongst others. Arraez, Gordon and Farmer are fine Utility types, but should not be out there everyday.
The bullpen, while always a concern (which teams isn't?), can be taken care of with failed starters and cheap FA's (just like every other teams).
Catcher will have to be addressed, but is probably not as big a problem as the posters on TD make it out to be, Houston won with Maldonado after all, while Philadelphia and Realmuto did not (I would rather have Realmuto though!!). Narvaez should be just fine, or a trade that doesn't totally empty the cupboard.
So, yes, I think the Twins can sign Correa without hindering team development, all reports indicate the young players like him and he is a good clubhouse presence. The other nice, shiny toys may not be affordable, but I think the team has the places in piece to win.
