I say NO. The guy actually claims to prefer passing over shooting. I believe him. I think most people would be surprised to find how rare a trait that really is in a PG. He mentally strong and focused and sees a much bigger picture than most guys do. Part of that bigger picture is to really appreciate the over-used, but no less meaningful, truism: There's no I in TEAM.
Doesn't mean Rondo will play well in game 5, but he's not going to let game 4 get to his head...
