Cardinals: Pros and cons of free agent targets for St. Louis

Carlos Rodon

Carlos Rodon is an ace, going 13-5 in 2021 with a 2.37 ERA in 132.2 innings for the White Sox, and following that up in 2022 with a 14-8 record and a 2.88 ERA in 178 innings of work as a Giant. St. Louis does not have this kind of starter in their rotation.
Rodon has swing and miss stuff, striking out 12 batters per nine innings in 2022, something that the Cardinals also sorely lack at the moment.
In recent years, it seems like left-handed pitching has an advantage at Busch Stadium, making a southpaw ace even more valuable for the Cardinals.

Injuries, injuries, and injuries. This is something Rodon has struggled with throughout his career, and although it improved the last two seasons, it just feels inevitable that he will struggle with those again. He has never eclipsed 180 innings in his career, and missed most of the year in the 2017, 2019, and 2020 seasons.
MLB Trade Rumors predicts Rodon will sign a 5-year, $140 million deal, putting him at $28 million a year. That is a lot of money to invest in a starting pitcher, especially if you cannot trust him to remain on the field.
The Cardinals already have question marks with health up and down their staff, why add another?
