Correa has been an average star on a great team for most of his career. Here are the Astros' bWAR leaders during Correa's career, 2015 to 2021:
1. Correa 34.1, 2. Altuve 32.7, 3. Bregman 26.1, 4. Springer 25.8.
There are injury concerns; because of missed time, Carlos' 162-game averages actually exceed his season bests in hits, home runs, RBIs and Ks. Last year when he was healthy, Correa's 7.2 WAR was right there among the top three position players, with Semien 7.3 and Soto 7.1.
He also was voted the Platinum Glove for best defensive player in the American League. That's the reason a below-average infield like Boston's could really use him.
