There are two venues for the Vegas Summer League: COX Pavilion and The Thomas and Mack Center. The Hawks are playing all of their games in Thomas and Mack Center (surely in tribute to Stacey Augmon). NBA TV is only broadcasting the games played at COX Pavilion.
That's where Summer League Broadband may come in for Hawks fans. $14.95 for the full schedule* of summer league games live and an on demand game archive. Budget accordingly, if applicable. For those on the fence about shelling out to watch scrimmages, I'll be attending the first three summer league games and covering them in this space for the price of free. Definitely a get-what-you-pay-for scenario.
*I've asked for confirmation that this package does include the games in COX Pavilion and will update once that is confirmed or disconfirmed.
