One thing I noticed is in the 4th, LeBron went full out ISO hero ball and tried to make it happen all by himself. In tight situations, you can see he doesn't really trust the other guys to come up big so he tries to do it all himself which has shown it doesn't really work.
At the same time you cant really blame him when his shooters are so inconsistent
I honestly think if Irving and Love were healthy they would have won this series.
But it doesn't matter too much as Cleveland are pretty much guaranteed to be in the Finals again next year. Learn from your mistakes...
