Rondo can't defend LeBron.
LeBron has improved his post game immensely since 2011 or whenever it was that Rondo had a few good possessions defensively against LeBron. Cavs big men are good enough offensively away from the basket to vacate the paint and let LeBron beat the hell out of Rondo. This is not a good situation.
Get Gerald Wallace on the floor to defend LeBron until Jeff Green comes back.
