Smart quarterback play and an impressive secondary are carrying Vanderbilt

My inbox is on the fritz thanks in part to what the ESPN research department is dubbing "Vandymania", which this week hinges on three must-know points:

• Vanderbilt's No. 19 ranking this week matches its highest spot in the last 50 seasons.

• The Commodores are seeking their first 5-0 start since 1941.
• Chris, Lee, Kirk and Desmond will bring "College GameDay" to Nashville for the first time ever this week.
