Lebron is notoriously reluctant to admit he has any fatigue issues or physical limits at all, so I take everything he says with a huge grain of salt.
As for Mancias -- do you really not know that before the season MANCIAS SPECIFICALLY LAID OUT A PLAN TO TAPER/REDUCE LEBRON'S MINUTES STARTING IN JANUARY? (See item 11 here --
http://www.ohio.com/blogs/cleveland...thoughts-on-lebron-minutes-and-books-1.727769 . This is mentioned in numerous other articles as well).
So yes, Mancias knows LBJ's body better than you, and Mancias advocated for exactly what I'm saying now -- reducing Lebron's minutes heading into the playoffs. It's common sense, and it's exactly what Lebron's trainer advocated and planned before the season.
