Jerry West won a Finals MVP in a losing effort.
I believe the best overall player in the Finals should win the MVP, regardless if their team wins or loses, but that won't happen because it isn't really politically correct to give the player on the losing team Finals MVP.
And yes, since it's now a requisite to be on the winning team to win a Finals MVP or a good team to win a regular season MVP, they are something of a team accomplishment, less so than rings, but team success does factor into their awarding. That's why I'm about done with player vs. player debates. So many factors outside an individual player's control can determine their "legacy." Pippen doesn't show up in Chicago, we're not talking about Jordan as the GOAT right now. The Lakers don't win their coin flip to draft Magic, he doesn't have 5 rings. Etc, etc.
It's a team game and we should really be arguing team vs. team. We've been at this Kobe vs. Duncan, Lebron vs. Kobe, player vs. player bull for 3 years now. We've approached the debate from every conceivable angle and then some. Time to retire it and move onto something else.
And in addition to the argument growing stale, Kobe tearing his Achilles killed my enthusiasm for this .
