The first 2012 Summer League game for the Spurs starts at 7PM CST -- or in less than an hour. You can purchase Summer League Broadband for $5 and that will allow you to watch all the games. Can't beat the price and the picture and sound quality has been great for me.

Anyways, this will be a very interesting game. The Spurs will apparently run their offense through Kawhi Leonard. Cory Joseph should also play a big role on this summer league squad.
If I'd have to guess the starting lineup, I'd say:
PG Cory Joseph
SG James Anderson
SF Kawhi Leonard
PF Eric Dawson
C Alexis Ajinca
Those first four players are probably a lock for the starting lineup. Ajinca's spot could go to whichever bigmen has been most impressive in the practice over the last few days.
The Hawks should be a good test. They beat the Wizards by 20 points in their first game despite Washington starting five NBA players. Atlanta's most interesting players are John Jenkins -- a great shooting swingman who was their first round pick. Keith Benson in the middle is a solid prospect, as is John Surna -- a rookie small forward. Other notable players on the Hawks are Gani Lawal (who was in Spurs training camp last season) and point guard Brad Wanamaker.
Should be fun
