Kurt Thomas is masterful at subtly walking people under the rim when going up for the boards.
Also, this TNT crew seems very pro-Chicago. They've been gushing over them all night, and Harlan is always ready with a huge "OHHHHH!" when Derrick Rose does one of his up-and-unders. On the other end, Jason Terry hits a jumper while being fouled and there's complete silence.
Nonetheless, this has been a good game despite being low-scoring. Neither team has much offense. Chicago's scoring is all Rose, with the occasional Kurt Thomas tip-in. Dallas only has two players - Dirk and Jet - who have any ability to create offense, and Dirk is pretty clearly nowhere near 100%.
