I think the word "choke" is appropriate here because I personally don't think most of his errors were due to being tired, they were mental errors. His bad passes, the offensive foul, most of the other turnovers. 6 turnovers in the final 9 minutes of a compe ive game by the best player in the league is and should be unacceptable. They weren't fatigue plays. Bad passes, mental lapses. That's choking.
If it were Kobe, if it were Jordan, they would have been and justifiably criticized similarly. Part of greatness is persevering through fatigue and other obstacles and still playing great. LeBron failed in that regard. I did say without LeBron the Cavs wouldn't even have been in the game. But, again, that doesn't absolve him for his play down the stretch. We are talking about the best player in the league. You can arguably blame a missed free throw on fatigue. You can't blame all 6 of his turnovers to fatigue. Great players play better than that in the same situation. And, when they don't, they will and should get criticized for it.
