Three tickets to a Mavericks game, on the court, before the door opens to the general public. Something he'd have to pay a couple of grand for to watch the Hornets, so he must be trying to get his daughter a date with a millionaire.
They are actually pretty cheap. I don't think he's asking for floor tix. You can just buy a regular ticket and then buy a "floor before the door" ticket which is a separate ticket that allows you to stand along the baseline during warmups. Those separate tickets don't appear to be very expensive.
For the record, I didn't know what he was talking about, so I googled it. And the above seems to be correct.
