Networks: ABC, ESPN

We're not going to mince our words here: Heather Cox is no spring chicken. She's been a sideline reporter since 1995, which makes her old enough to be the mother of some of the young things on this list. (She is a mother, by the way, but her kids are not on this list.)
But you know what? It's 2012, and moms are hot. Heather Cox has been doing what she does for so damn long because she's damn good at it. She gets the big game in college football, Saturday nights on ESPN/ABC with Brent Musberger and Kirk Herbstreit, and you know they wouldn't have it either way (well, not since Erin Andrews moved on). Sometimes you want an experienced mama redhead down in the trenches doing your dirty work.
The young, young things? Keep 'em up in the booth. For their own safety.
