Heat-Lakers was Lamar Odom in Miami vs. Kobe in the white jersey (Odom only spent 1 year in Miami), and the Cavs-Heat pic was Odom in Miami vs. Carlos Boozer in the first year of that Cavs jersey.
I mean, Odom vs. Boozer in the East only happened that year (Both went West in the offseason) and Odom/Kobe have either been Laker teammates or playing on different LA teams save for that brief Dallas stint
It's not just rare uniforms- it's rare team matchups, and there have been so many instances of one-year only situational matchups, team or individual.
