Personally, I see a single play (4th quarter) where the refs could have called a foul on him. I'm not entirely sure that was a foul though. But I see no evidence whatsoever LeBron was protected in game 1. In game 2, perhaps a play with Bibby, but I'd need to see a replay from a better angle.
Still, not a lot of evidence to support the claims he's being over-protected.
