More just in the scope of defining a decade. It is arbitrary, but people tend to view eras this way. Like how the 90’s was Jordan’s (even though he won playoff games in the 80’s) and to your point, how LeBron’s longevity has spanned 3 decades.
It’s not meant to diminish anyone, it’s quite easy to look up how many total games these duos won together. It’s just interesting to group it by decades.
This list is also excluding the 15 games Tatum and Brown won together in 2018 and 2019 and I’m a Celtics fan, there’s no agenda with this post.
How many playoff games they won together in that decade
