Assuming we continue to view Anthony Davis as a power forward, which was always his stated preference during his time in Los Angeles, then the bar for best true center of the LeBron James era has been remarkably low. Now, the arrival of Deandre Ayton means he probably immediately takes over that unofficial title.
It's honestly not like it was a particularly hard title to earn considering the past candidates. Marc Gasol, Andre Drummond and Dwight Howard all offered solid moments during their time in Los Angeles, but were far removed from their peak years when they suited up in the purple and gold.
