Yes and no. But first some perspective. In my estimation, the Nostalgia Era started in 2011 and continues to present day. The reason I dub it the Nostalgia Era is because the San Francisco Giants regularly rewarded the integral players in their championship runs with large contracts or re-signings.
This isn’t necessarily nostalgia, per se. You could make the argument that it was fair and compassionate, two things that many huge sports franchises are not.
Rewarding someone like Matt Cain, who was one of the best pitchers in the National League at a bargain price, with a huge contract was absolutely fair.
