Lebron is a lot like Dwight, he could be even more amazing if he stuck to what he is good at. At PF Lebron is unstoppable but he wants to be the SF GOAT and avoid fighting TD for PF GOAT. Honestly if Lebron played PF full time they would be first seed in the East.
He can play that from the PF spot though, the ball just goes inside out. If you look at the Miami days the 3 timed he won a ring was when Bosh played C and he played PF. And if he made Love the starting C he should have been pf and made thompson come off the bench, and then Jae Crowder wouldn't be playing out of position.
