College football lacks a hot stove season like MLB, or free-agency madness like the NBA and NFL. But there's still an appetite to speculate about what's next for the sport's most prominent figures -- the head coaches.

The season is finally getting started, but it's never too early to start debating coaches and potential moves. We put those questions to coaches around the sport, as well as administrators and other industry insiders.

Here's a look at three coaches and what could be coming for each in 2018 and beyond.

How much longer will Nick Saban coach?

Alabama athletic director Greg Byrne, speaking last week on the Paul Finebaum Show, described Saban as "66, probably going on 50." It's hard to argue. Saban is in great shape, remains sharp and energetic with his players and the media, and shows no signs of slowing down.

"What the hell else am I going to do?" Saban told ESPN earlier this year.

Many of Saban's fellow coaches and former colleagues see him coaching into his 70s, maybe well into his 70s.
