The countdown is on. We're only 100 days until Alabama begins its defense of the national championship.

The Crimson Tide opens the season against the USC Trojans on Saturday, September 3. The kickoff time for that game has already been set for primetime and air nationally on ABC. The two teams will play in AT&T Stadium as part of the Cowboys Classic.

We all have a long summer of waiting and debating ahead of us, but this hype video from AL.com is just what you need 100 days out. It'll have to hold you over until SEC Media Days arrives in early July.
