Pre Game at the Rock question

[george_allen]

Happy New Year - newbie to the forum here. Was hoping for a little info – my son asked me to take him to the Prudential Center to see the Nets play the Thunder later in January. I haven’t been to NBA game in a while and was wondering, if we show up early, can we watch warm ups and if there’s a opportunity before the game to get an autograph or 2?
Thanks in advance,
