Every year we must explain to students the "Five W's" of college football turnover.

Who? What? Went where? Why?

Things don't stay the same very long. Players cycle out every four or five years, and for coaches, the grass is usually greener anywhere the green involves money.

Here's a look at some new faces in new places:

Defensive coordinator Will Muschamp couldn't wait out his coach-in-waiting position at Texas and jumped at the chance to replace Urban Meyer at Florida. Muschamp has no previous head coaching experience. Is he the next Meyer or the next Ron Zook?

Muschamp hired former Notre Dame coach Charlie Weis to run the Gators' offense.

Mack Brown responded to last year's 5-7 record at Texas by replacing five assistant coaches. Brown's big hire was Bryan Harsin, who ran Boise State's electric blue offense.

Brady Hoke parlayed program resurrections at Ball State and San Diego State to land the Michigan job that Rich Rodriguez left a shameless shambles. Hoke is a former Michigan assistant and the kind of meat-and-potatoes guy who can pick up the Wolverines while Ohio State is down.

At San Diego State, Rocky Long steps up from defensive coordinator to take Hoke's spot.

Jim Tressel's shocking offseason resignation left the Ohio State program to assistant coach Luke Fickell, who must navigate it through its worst scandal in years. Fickell, only 38, says the good part is he didn't have much time to worry after Tressel stepped down on Memorial Day.

"The situation arose, and, obviously, I had to stand up," he said.

Al Golden, who did a remarkable job at unremarkable Temple, was assigned to return Miami to its former greatness. What is he to do now after the booster scandal broke?

Stanford, coming off a 12-victory season and romp over Virginia Tech in the Orange Bowl, lost coach Jim Harbaugh to the 49ers. The Cardinal went in-house and hired offensive coordinator David Shaw.

His first year, with Andrew Luck returning at quarterback, should be on autopilot. He will need some luck after that.

Randy Edsall took Connecticut to the Fiesta Bowl and then left for Maryland, which fired Ralph Friedgen after he was named ACC coach of the year. Paul Pasqualoni, who won 107 games at Syracuse before he was inexplicably-in-hindsight fired, takes over at Connecticut.

The Dan Hawkins era/error is finally over at Colorado, which has asked alumnus Jon Embree to lead the program into the Pac-12.

Lane Kiffin, famous for his nomadic nature in drive-by stints with the Oakland Raiders and Tennessee Volunteers, returns for his second year at USC.

"He's in the same place for two years in a row now, which is good," USC quarterback Matt Barkley quipped.
