I'd say YES - LeBron James can most definitely win Finals MVP if the Warriors win.
What he has done (minus KLove and Kyrie) is simply AMAZING.
He has shot nearly 40% from the field over 34% from deep. His Finals PPG is roughly 37, over 12 rebs, almost 9 assists, as well as a steals roughly 1 block (0.6 Blocks, I rounded up).
While he hasn't shot particularly well, he's had really just that one 11-35 FG game (and CLE won that one). He's done this without any "Stars" next to him.
Even with Kyrie's performance in Game 1, while good - he wasn't even 100% healthy as we've found out. I'm doubting that Kyrie was even close to 100%.
As I compared Jerry West' stats, while outstanding, when he won Finals MVP in a losing effort - he had Wilt AND Elgin present. My guess is that if LeBron James had either Kyrie or KLove present this series could be over, in CLE's favor - right now.
So, "IF" Steph gets the nod for Finals MVP - his stats are the following, for the 5 Finals games (Thus Far):
Over 26 pts, 6 assists and 5 rebounds. While great numbers, he has had Draymond, Klay and the rest of the team HEALTHY - as well as Home Court Advantage.
Both Steph and Lebron had 1 game this series where they both shot abysmally.
As a lifelong Celtics Fan who has enjoyed LeBron's past failings VS BOS and who derided him for his "Decision" - I have to give it up for the man in these finals:

If CLE sends this series back to GSW LeBron James may not even need this discussion.
