Democratic National Convention @ 8pm, PBS: Did you know that they had to move the start of the NFL season because of this? WTF!

Hard Knocks @ 10pm, HBO: Season finale for a show that’s been a bit up and down.

Late Show with David Letterman @ 11:30pm, CBS: Dwyane Wade and Claire Danes stop by the Ed Sullivan theatre.
