Maybe it just wasn't properly advertised? I went to a Patrick Beverley signing and the line was out the door and all down the hall way strip center. Probably a 100+ people, pretty big for just Pbev.
When I went last year for Hakeem, it was set up in front of Valenti which is the suit shop that Murphy gets all his loud suits from. The t-shirts and cards they gave you to get signed all had advertising for them on it. I think this is an event that Calvin Murphy is throwing not the Houston Rockets. Therefore it is not very well publicised. Last year when I went for Hakeem, they would only let him sign the card and/or t-shirt they provided. Although I did see him make one exception for a handicapped kid in a wheelchair. What a nice guy.
I know the Toyota center fan fest thing is cancelled...also weird that this was originally on the same day as fan fest..
