Comparing athletes across sports is pretty fruitless, so any award that attempts to do so will ultimately resort to being a popularity contest. Also, I can't talk about the WNBA MVP award, since I don't follow the league, but historically the NBA MVP award has itself been something of a popularity contest, with guys like Derrick Rose and Allen Iverson winning, though that's less of an issue nowadays, as voters typically have more knowledge of advanced stats and their value.
My point isn't who was or wasn't the best athlete in a given year, it's about what the
American sports media narrative was at the time, which is interesting to me, from a media studies perspective. My argument is that the American sports media narrative itself has been retconned. It'd be like if the media tried to convince you that a movie was considered the best during the year it came out, but another movie won way more major awards and had way better reviews from critics and the public at the time. Seeing history being rewritten before your very eyes and watching the past be storified is fascinating. Young people who don't remember the time, older people who weren't following or whose memories have faded will often just accept this new version of events. Obviously sports history isn't particularly important in the grand scheme of things, and I don't exactly lose sleep over it, but it's a curiosity, and has implications for other more important areas, which we see people debate in The War Room all the time.
Plus, I don't think a European NBA player has ever been the best European athlete, never mind the best athlete overall. Hell, I don't think
any NBA player has ever been the best athlete overall.
Also, regarding the AP award: "The awards are voted on annually by a panel of AP sports editors from across the United States, covering mainly American sports."
The Laureus World Sports Award for Sportsman of the Year is a better representation of the global sports media narrative, but it only goes back to 2000, and I'm obviously less familiar with the narrative around the world, so I don't know how much has been retconned, but given my limited understanding, it doesn't look anything like as brazen as the AP equivalent. It's also interesting that nobody from the top 5
highest-revenue sports leagues has ever won.
