I start dooling and put on him williams/holiday, get him to harass them all day long, freeing up rondo to play the 2, only problem is if they run plays out of the post on rondo, which you may be able to counter act by play steamer abit and having guard the rim.
I fell rondo is a confidence player, as soon as they score on him, his confidence goes down and rest of his game suffers, game seven will say alot about rondo.
