If you go to a team page on baseball-reference, you'll see pictures of the top 12 players for each season, sorted by Wins Above Replacement. It can be a fun trip down memory lane.
Click on the 2015 Giants and you'll see Matt Duffy, Jake Peavy, Chris Heston and George Kontos mixed in among the longtime core Giants. Go back to the last title team and you'll see photos of Jean Machi, Angel Pagan and Gregor Blanco. Pull up the legendary 2010 team and the first two photos are of Aubrey Huff and Andres Torres.
The 2019 team didn't provide nearly as much value as most recent Giants clubs, but if you pull up the page for last season, the first thing you notice might be a little scary.
