Lebron was thinking too much, instead of just playing hard:
*notice how slowly he's moving as he dribbles, instead of moving at attack speed
*he disregarded how he only needed 2 pts, so he shot a jumper from near the 3pt line instead going down the middle to the basket against much smaller and weaker defenders you see in the lane
*he played into the sole strength of Rudy Gay/ability to always contest Lebron's long jumper
*he refused to force his will, by using his strength/his power over the thinner weaker Rudy Gay.
