"It's not often that rookie free agent center Garret Siler is forced to look up to someone on a basketball court. But that's exactly what happened to the 7-footer Wednesday when Los Angeles Lakers center Andrew Bynum cut through the door of the Hawks' practice facility to get a workout in at the John 'Beans' Beckett Invitational. Bynum and Siler matched up in two different games and Siler acquitted himself well, neither big man dominated the action -- that honor belonged to veteran pro Jerry Stackhouse (who has been on a tear this week on both ends of the floor against players much younger). Siler said he was just happy to have the chance to compete against a pro of Bynum's caliber. 'This is the best test for me to see guys like [Hawks center] Al Horford and [Bynum] out here,' Siler said. 'It helps mentally when you can say, 'hey, i'm d'ing this guy up and he plays for the world champions. He's got a ring.' So if you can hold your own going against and he's not just destroying you, hey, you must be doing something right.' "

Apparently he's also more in shape and slimmed down, while still being huge.
