It will be an interesting Hot Stove season for the Cards if they plan to improve for 2024. Bring Winn up on Sept. 1st and throw him out there as much as possible for the last month. See if the guy is going to hit at all and get him used to being the everyday SS next season.
Start looking to package O'Neill, Burleson and a few others not named Walker, Noot and Carlson to either get pitching or another quality outfielder that has some power. No more dumpster diving on starting pitching, go sign 2 if not 3 starters that can give you quality starts with the ability to strike people out, if that is a #1 and a #3 starter or three #2's whatever, but spend the damn money and get some pitching.
Decide what you are going to do with the catching problem and if you want Contreras to be the full time DH, then trade the softball players for someone that can hit. Keep either Edman or Donavon and move the other. Move Gorman fulltime into second, and let him and Winn be the up the middle convo for the next decade.
One more year of Goldschmidt on contract and don't want to have a second bad year in a row with Arenado starting to leave his prime. This offseason will tell us how serious ownership is in winning vs turning a profit. It shouldn't be overly difficult sign a $20-$25M per year starter such as Nola, Giolito, Snell, Urias, or S Gray.
Then, and this will hurt a bit, but you're going to have to trade Donovan and O'Neill/Burleson/Herrera for someone like Logan Gilbert or more realistically Bryce Miller or Bryan Woo. Could also try a lesser trade such as O'Neill/Carlson and Edman for a year of Shane Bieber but his contract and recent trend makes him less likely to help as much.
Commit to better defense by rotating Gorman and Walker at DH when Contreras is catching. Catch Contreras 80 games or so with the idea that if you make the playoffs he catches then to lengthen the lineup.
Can make some minor trades or signings to shore up an additional arm in the bullpen but the below should be able to compete in the Central no problem:
Nola
Mikolas
Gilbert/Miller/Woo
Matz
Liberatore/Z Thompson/Hudson/Graceffo
CF Nootbaar
1B Goldy
3B Nado
DH Gorman
C Contreras
RF Walker
LF O'Neill
2B Edman
SS Winn
