Gates open an hour before the game but season ticket holders can get in 90 minutes early. If you want to be close to the front of the line, I would suggest standing outside the main entrance no later than 20 minutes before gates open. Off the top of my head, I believe you will want to drop down around section 108. If that's not the exact section, just drop down and slide over (so when you scan your ticket go left and keep walking). I got autographs from the Pistons earlier this season and they were a really good signing team. Good luck!
