No jersey, just the Spurs hat. My wife also had her Spurs hat on (she's a bandwagon jumper).
Portland does a lot of piping in sound these days...I think the crowd did get a little loud when the Blazers made a little run to either tie or down by 1-2 at the end. But it's still nowhere near what it was when Clyde, Jerome, Terry, Buck, and Duck were on the floor. My parents had season tickets from 1971 (2nd year of existence) to I believe 1998. I grew up with them all, even was a little 3 year old when the Blazers won it all in 1977.
Terry got a nice ovation when they showed him on the video screens, he did wave to the fans. Clyde, Jerome, Terry, and Buck are considered God-like still around here.
