Well this was surprising. Buster Posey, much like several other members of the 2021 Giants, seemed like he revived his career last season. His .889 OPS and 140 OPS+ were the best he had put up since he won National League MVP in 2012. He was about to be a hot commodity on the free-agent market, but it seems like he's ready to call it quits. If this truly is it for Buster Posey, then what a remarkable career it was. The expectations for Posey were sky-high when he was drafted out of Florida State, and he exceeded every single one. He's a seven-time All-Star, a four (possibly soon to be five) time Silver Slugger, a Gold Glove winner, and the face of the Giants franchise for well over a decade. When you think about the heyday of San Francisco Giants baseball, Buster Posey is one of the first people that comes to mind, which makes sense because the last time the Giants won a World Series in which Buster Posey wasn't on the roster was 1954.
Before anyone asks, yes, Buster Posey is a Hall Of Famer. Catcher is still a very odd position to gauge because advanced analytics have not caught up to framing metrics. Throughout his entire career, Buster Posey was one of the best game callers and pitch framers in the sport. Still, he'll end his career with a 44.9 bWAR, which is higher than future Hall of Famer Yadier Molina, and he played far fewer seasons than Yadi has. Even if analytics don't support it, to me, Buster Posey belongs in Cooperstown. He was the best at what he did for a long time, and I hope he enjoys retirement.
