Recruiting in college football is downright nasty. It is a cutthroat, cannibalistic big business that is microscopically analyzed by fans, administrators and media members alike. The Big Ten's recruiting trail is chalked full of intriguing storylines.

Preseason prognosticators like Athlon Sports — the most accurate college football preview magazine on newsstands — use many things to predict what the coming football season will look like. Returning starters, scheduling, historic trends, coaching, pending off-the-field issues and, of course, recruiting rankings all help Athlon editors predict the future of college football.

The BCS just put a bow on its 15th season of action and Athlon has dissected the numbers and reviewed the tapes of all six BCS conferences in order to rank the best each league has had to offer. Which Oklahoma team was the best of the decade? Which Florida team was the toughest to stop? How do you rank the Florida State teams of the late '90s? Which Miami team was the best? How about those loaded USC teams? Alabama vs. Auburn?

The debates will rage on for decades, but here is Athlon's two cents. Here are the Top 12 Big Ten teams of the BCS Era (1998-present):

College football’s coaching carousel was in full effect this offseason. Thirty programs will have a new head coach in 2013, ranging from Arkansas, Auburn, Kentucky and Tennessee in the SEC to FBS newcomer Georgia State in the Sun Belt.

Recruiting rankings are an inexact science, and even the experts will admit that. It is virtually impossible to measure heart, work ethic, mental focus and self-awareness in 17- and 18-year-old kids. Especially, in the face of the most important decision they will ever make.

The start of spring practice is still over a month away, but college football coaches have already turned the page from 2012 to 2013. With the passing of the NFL Draft deadline and new recruits coming in after Signing Day, coaches have a good idea about their roster and some of the holes facing their team.

The Big Ten had a year to forget in 2012. Two of the conference’s best teams (Ohio State and Penn State) were ineligible to compete for the postseason, while Michigan State underachieved and finished with a 7-6 mark.

It is never too early to start looking ahead to next season. Especially now that Alabama is college football’s 2012 National Champion. This season featured huge showdowns between the ACC and SEC at the end of the year, Notre Dame battling with the Big Ten or Pac-12 all season long and a host of other important non-conference showdowns. Each and every year, a variety of intersectional matchups mold the national championship landscape or add a chapter to long and storied rivalries.

Athlon Sports starts marking up the 2013 calendar with key non-conference games to watch:

Johnny Manziel set the college football world on fire this year and it led to the first redshirt freshman winning the award. Johnny Heisman confirmed his amazing season by putting on a record-setting show in the Cotton Bowl win over Oklahoma. But is the redshirt sophomore-to-be the front-runner to win Heisman considering only once in 77 years has someone won the stiff-armed trophy a second time. And that was in 1975 (Archie Griffin).

The opening of three key SEC jobs this season -- Arkansas, Auburn and Tennessee -- sparked debate within the Athlon office, and, it seems, through rabid SEC fans.

Which job is the most desirable?

It’s a loaded question, for sure. Tradition, resources, commitment, recruiting base, competition level and other perks and challenges all come into play.

Two years ago, we ranked every coaching job in the country in our preseason annual. Much has changed since then, not least of which conference affiliations.
