I liked what Tony did overall defensively out there. Now you can see why players can't guard Gordon closely, he has an uncanny ability to throw his body around to create contact.
Tony did foul Gordon in the 3 point line, right after he had forced him out of bounce, and to me it looked like Tony jumped straight up and Gordon was on top of Tony, so the foul was inevitable. So what would've been a great defensive play (and was) turned to another "dumb" play by Tony. Plenty of people have fouled 3point shooters in this series, to solely focus on this Tony transgression when in truth it was a great defensive play.
What I like most of what Tony is doing out there defensively, is that he recovers well. If Gordon blows by Tony, after 1 or 2 dribbles, Tony is right back contesting the shot... but Gordon is simply making some unreal shots.
What I would do though, when Tony is in there, I would put him on either Rose and Hinrich, and put Rondo or whomever is out there on Gordon.
I'll say this though, if the team is not moving the ball as it should (and it hasn't done this pretty much the whole series), then House is useless out there as he can't guard ANYONE from the Bulls. Don't insert him any more in this series.
