If the Phillies get one of the big four SS, it should be Correa IMO. He is the best and the youngest, as he will be playing almost the entire 2023 season as a 28 year old. So he should be in his prime, and also 1- 3 years younger than the Phillies' current core. One issue with the 2008 team was that most of its core was practically the same age, so most of them started to go over the hill in 2012. He will likely be the most expensive. but the Phils have the $$.
I do think Trea Turner would be a good alternative. He will play half of the 2023 season as a 29 year old. However, as noted above he would cost the Phils $ and draft picks.
If the Phils do not go with any of the big four, I think they would get as much out of a Maton/Sosa platoon as they would with Segura, and be able to save $ for pitching. Jean will be playing the entire 2023 season as a 33 year old, where the likelihood of a large drop off starts to become significant.
