He is a MVP but not the leader of the LA Lakers, it's always been Lebron who is the leader of every team he played and Davis although has some exceptional talent hasn't been able to enjoy the success he had with Lakers already. They are on the lead now, 2-0 which gives them a huge chance of winning but it's still early to say that they will win, they still need to win 2 more games and then that's it, it's gonna be AD's first NBA finals appearance.
I wish to see Anthony Davis too win in MVP because Lebron had been MVP already. It is an experience in his side this is why I think it is better for lebron to give way this to Anthony Davis. Anyway, AD too had shown good playing skills and I think this is enough for him to win the MVP. The 2-0 advantage for them is an indicator that lakers team is truly a good team with strong players having a high chances to wn championship in this season.
It would be tough call even if people think Davis is the most valuable player in Lakers we can't expect the judges to vote the same way. Remember that the one who won Finals MVP is Iguodala during the 2015 Finals and not Stephen Curry who among the fans thought he will be winning that title. It would really depend on how the judge view things and I think what they would be looking is how they are contributing all around to the team which I think Lebron James is checking all the boxes based on his stat line.
