How do we define MVP? If it's the best player in the league, Isaiah's not in the conversation.
If it's the player who has been most instrumental in the team's success, he's top-5, possibly top-3.

Part of the problem with the MVP is that everyone defines it differently and even those people define it differently year by year.
For the most part the factors considered are:
Overall talent/best player: You don't have to be the best in the league, but you have to be in one of the top tiers in terms of overall best players. Still, being the best player in the league means you are never ruled out completely.
Wins: How well your team does. Typically, the MVP goes to a player from again, not necessarily the best team, but one of the best teams in the league.
Narrative: Is there a good story behind your performance for the season? How does your story stack up against the other candidates?
Momentum: Have you won the award previously? If so, how recently and how many times? Sometimes voters tire of a certain player being the MVP (see Jordan, Lebron) and vote for other players having great seasons.
Most Valuable: How good would your team be without you relative to how other teams would be without their star players? Are you literally the "most valuable".
