The San Francisco Giants are yet to be good on the diamond with Buster Posey at the helm as the team's president of baseball operations. But Posey has built so much goodwill with both the Giants franchise and its fanbase after he spent the entirety of his illustrious career with the team that he has certainly earned the benefit of the doubt as he gains more and more experience in his executive career.

Posey will be eligible for the Hall of Fame as a member of the 2027 class. He spent 13 years with the Giants, won three World Series titles with them (2010, 2012, and 2014), and emerged as a legitimate leader that the entire locker room looked up to.

The intangible impact he had on the Giants franchise is unmistakable. He was elite behind the dish and called games for pitchers at such a high level that pitchers, like Jake Peavy, credit him for getting the best out of them. In an appearance on MLB Network, Peavy praised Posey for making the game easy for him to the point where he recorded an ERA of 2.17 in 12 appearances after San Francisco acquired him at the trade deadline.

“It's because [Buster Posey] was calling the pitches,” Peavy said.

Prior to the trade, Peavy had a 4.72 ERA on the season in 20 games with the Boston Red Sox. He was already 33 at the time, so some decline was understandable, but he got a new lease in life with the Giants and helped them win their third World Series title in five years.

Peavy would only have two seasons left in the big leagues, but for a good stretch, he turned back the clock thanks in large part to his partnership with Posey.

Posey does not have the most eye-popping counting stats. He only had 158 home runs and 729 runs batted in for his career, although he did finish with a batting average of .302. But the Giants would not have won big without him, and the impact he had that stats could not account for must not go unnoticed.
