It's a well-known fact that the Knicks stink at defense (they rank 22nd), but this just looks absurd. Every time down the floor, the Mavericks essentially have free rein to do whatever they like. In the lane, mid-range, on the fast break. You name it, the Knicks are gifting it to them. The Mavs have 32 points, but that doesn't show the sheer ineptitude that the Knicks are displaying.
Zach Randolph is giving away the lane. He averages a block every five games, and this isn't looking like that game. He isn't even challenging when guys come into the lane and seems satisfied watching the Mavs dribble around.
On the fast break, Knicks players aren't getting back at all. A lob up the floor to ason Terry happened twice and there was little resistance.
Basically, if the Mavs want to keep running away with this, they need to attack, attack, attack. The Knicks obviously aren't feeling the need to muster a defense to it, so why not exploit it?
