ESPN Preseason Power Poll: No. 8 Aggies

We're rolling out our preseason poll this week with five teams each day.

Here's where the Big 12 teams checked in so far.

Our poll was put together based upon ballots submitted by 25 ESPN.com college football analysts, columnists and reporters, including yours truly.

After our poll is finished this week, I'll unveil my personal top 25 ballot on the blog.

Next up is Texas A&M at No. 8.

Texas A&M: The Aggies were a different team last season once converted wide receiver Ryan Tannehill took over at quarterback, winning six straight including a win over Oklahoma. They return the most starters in the Big 12, including their top two running backs and wide receivers. The team is actually losing only nine receptions from its receiving corps from last year. Matt Allen, last year's starting center, is the only change on offense. The defense lost leading tackler Michael Hodges and Von Miller but all three units -- defensive lineman, linebacker and defensive back -- stack up well against the rest of the Big 12. The Aggies' expectations are as high as they have ever been under coach Mike Sherman, but anything less than a Cotton Bowl win will be a huge disappointment. -- Ryen Russillo, ESPN Radio
