How good is your team's quarterback room? It's a question that can dictate a season and determine job security. It's a question that is answered through recruiting, development, coaching hires and sometimes just dumb luck, but the answer is achieved over time.

Ohio State needed its entire quarterback depth chart to win the 2015 College Football Playoff National Championship. Florida's inability to find a steady quarterback has played a part in costing two coaches their jobs. Jake Fromm and Tua Tagovailoa started last season as backups for Georgia and Alabama, respectively, but battled it out for the national title in January.

So, I set out to rank the top 25 quarterback rooms in the college football right now. This isn't a list of the top starting quarterbacks. It's a ranking that seeks to answer questions like: Who is best equipped to absorb injuries under center? Who is set up for success beyond the 2018 season? Who has a quarterback coach that will get the most out of his room? Who has recruited well at the position?

Here's your top quarterback rooms for the 2018 season.

1. Washington

QB coach: Bush Hamdan

Depth chart: Jake Browning (Sr.), Jacob Eason (Jr. -- eligible in 2019), Jake Haener (rFr.), Colson Yankoff (Fr.), Jacob Sirmon (Fr.)

Browning has his limitations, but he's amassed almost 9,000 career passing yards entering his fourth season as starter. Then, the Huskies get two years of an even more talented QB in Eason. Then, in 2021, Chris Petersen gets his choice of what will likely be three former four-star arms to take over. Hamdan is also a rising star.

2. Alabama

QB coach: Dan Enos

Depth chart: Tua Tagovailoa (Soph.), Jalen Hurts (Jr.), Mac Jones (Soph.)

When Tagovailoa wins the starting job, he'll emerge as one of college football's best quarterback talents, and he's around for at least one more season. This also makes Hurts the most accomplished backup in college football. Even if Hurts transfers after the season, Jones will give Alabama solid depth in 2019 and beyond. So, too, will Tua's little brother Taulia, a 2019 Tide commit.

3. Penn State

QB coach: Ricky Rahne

Depth chart: Trace McSorley (Sr.), Tommy Stevens (Jr.), Sean Clifford (rFr.), Will Levis (Fr.)

McSorley is a Heisman Trophy candidate and Stevens is as good as any backup in college football. Penn State is air tight for the next two seasons, but after Stevens, someone will need to step up and it's likely Levis or 2019 commit Ta'Quon Roberson.

4. Clemson

QB coach: Brandon Streeter

Depth chart: Trevor Lawrence (Fr.), Kelly Bryant (Sr.), Chase Brice (rFr.)

Regardless of whether Lawrence is starting against Furman on Sept. 1, here's betting he'll be starting by the time Clemson is playing in the College Football Playoff. Clemson has the former No. 1 player in the country for three more seasons, and Brice and Bryant will serve as solid No. 2s along the way.

5. Georgia

QB coach: James Coley

Depth chart: Jake Fromm (Soph.), Justin Fields (Fr.)

Georgia has the best two-man depth chart in college football, but behind Fields is an abyss of walk-ons with no quarterback committed for 2019 and beyond. The good news is that Fields and Fromm will (probably) be around beyond 2018, but Kirby Smart has got to find some depth quickly.

6. Michigan

QB coach: Pep Hamilton/Jim Harbaugh

Depth chart: Shea Patterson (Jr.), Brandon Peters (Soph.), Dylan McCaffrey (rFr.), Joe Milton (Fr.)

This ranking is a dramatic uptick for the Michigan QB room from the past two years, but Patterson has first round NFL Draft pick potential as a transfer, Peters proved last year he's of starter quality and McCaffrey and Milton are both young with a ton of upside. With this group, Harbaugh has no excuses. Time to live up to his QB reputation.

7. Northwestern

QB coach: Mick McCall

Depth chart: Clayton Thorson (Sr.), Hunter Johnson (Soph. -- eligible in 2019), Adian Smith (Soph.), Andrew Marty (rFr.), TJ Green (Jr.), Jason Whittaker (Fr.)

The transfer of Johnson really elevates the Northwestern room. He's an NFL-level talent who will have three years of eligibility remaining after a season that likely produces an NFL pick in Thorson. McCall's presence matters too and this room could give him his third and fourth NFL Draft picks in just 10 years.

8. Mississippi State

QB coach: Andrew Breiner and Joe Moorhead

Depth chart: Nick Fitzgerald (Sr.), Keytaon Thompson (Soph.), Jalen Mayden (Fr.)

You're getting huge, athletic dudes with big arms under center for the foreseeable future in Starkville. Fitzgerald has a really good backup in Thompson, and 2019 commit Garrett Shrader is the most athletic big quarterback in his class. Throw in a Moorhead bump on this ranking as well because of his QB-friendly system.

9. Michigan State

QB coach: Brad Salem

Depth chart: Brian Lewerke (Jr.), Rocky Lombardi (rFr.), Theo Day (Fr.), Micky Macius (Sr.)

Michigan State has been incredible developing QBs under Mark Dantonio, and Brad Salem has played no small role in that. Lewerke was a breakthrough, first-year starter last season and brings arm and athleticism to the position. He's got at least one more year and the position looks sturdy beyond the starting job with Lombardi and Day.

10. Florida State

QB coach: Walt Bell

Depth chart: James Blackman (Soph.), Deondre Francois (Jr.), Bailey Hockman (rFr.)

Heading into the 2017 season, there was talk of Francois as a potential NFL Draft pick as a redshirt sophomore. After a missed season because of injury, he's in a battle just to win his starting job back from Blackman. That may be bad for Francois, but it's great for FSU's room. The Seminoles new QB coach overachieved with Maryland's talent and should do well with Florida State.

11. Oklahoma

QB coach: Lincoln Riley

Depth chart: Kyler Murray (Jr.), Austin Kendall (Soph.), Tanner Mordecai (Fr.)

Riley has the magic touch right now and though the Heisman winner is gone, he's got an even better athlete returning in Murray and a starter-quality option in Kendall. Murray is off to the MLB after this fall, but with Mordecai and 2019 commit Spencer Rattler in the pipeline, the room has a lot of long-term stability.

12. Ohio State

QB coach: Ryan Day

Depth chart: Dwayne Haskins (Jr.), Tate Martell (rFr.), Matthew Baldwin (Fr.)

Haskins has been outstanding in flashes as a backup and may be good enough to be one-and-done to the NFL after 2018. Martell doesn't have the physical features for the NFL, but he could be scary good as a college quarterback. Their coach turned down an NFL offensive coordinator job to stick around, so they're in good hands.

13. Auburn

QB coach: Chip Lindsey and Gus Malzahn

Depth chart: Jarrett Stidham (Jr.), Malik Willis (Soph.), Joey Gatewood (Fr.)

Stidham may be a 2019 first-round pick if he has the junior season we expect this fall, but Auburn has a lot of questions behind him because there's not a viable passing threat waiting in the wings. There is, however, a pair of really talented runners in Willis and Gatewood, and Gus Malzahn knows how to utilize that skill-set. Reinforcements are coming through the air, too. 2019 commit Bo Nix can spin it.

14. NC State

QB coach: Eliah Drinkwitz

Depth chart: Ryan Finley (Sr.), Matt McKay (rFr.), Devin Leary (Fr.)

Finley may have been an NFL Draft pick had he departed after the 2017 season and he's tracking to be a pro after this year as well. Behind him, NC State has done a good job in getting some competent talent. Leary has a huge arm and McKay is a big, athletic dude who presents a different look for defenses.

15. Stanford

QB coach: Tavita Pritchard and David Shaw

Depth chart: KJ Costello (Soph.), Davis Mills (rFr.), Jack Richardson (Jr.), Jack West (Fr.), Tanner McKee (2018 signee)

If not for some injury questions, this is a top 10 room. Costello really gave Stanford some juice last season when he took over under center, and he should be improved in Year 2. Mills was ranked higher than Fromm and Tagovailoa in the class of 2017, but has dealt with injuries. Those two could solidify Stanford's quarterback room for the next three years and by the time they're gone, McKee will be coming off of his Mormon mission with more arm talent than all of them.

16. Kansas State

QB coach: Collin Klein

Depth chart: Alex Delton (Jr.), Skyler Thompson (Soph.), Samuel Wheeler (Fr.), John Holcombe (Fr.)

Kansas State upset Oklahoma State last season behind Thompson and nearly upset Oklahoma with Delton. Whether it's Delton's legs, Thompson's arm or some balance of both, Kansas State has plenty of capable options under center.

17. Duke

QB coach: Zac Roper and David Cutcliffe

Depth chart: Daniel Jones (Jr.), Quentin Harris (Jr.), Chris Katrenick (rFr.), Daniel Karlin (Soph.), Gunnar Holmberg (Fr.)

Jones has two more years of eligibility left, but there's buzz coming out of Durham that he may be poised for the type of year that springboards him to an early NFL Draft departure. He's got the tools and Cutcliffe should know. Harris is a solid backup and there are some intriguing arms coming up, but Duke's pursuit of Hunter Johnson in the spring indicates that perhaps the next sure thing isn't on campus yet.

18. Oregon

QB coach: Marcus Arroyo

Depth chart: Justin Herbert (Jr.), Braxton Burmeister (Soph.), Tyler Shough (Fr.)

Herbert is probably the most unique talent in the country at the quarterback position and has No. 1 overall NFL Draft pick upside. If injury hits Herbert though, last season showed that the depth chart is not there yet. Burmeister and Shough have some work to do to stabilize the room long term, and this is likely the last year Oregon gets with Herbert.

19. Iowa

QB coach: Ken O'Keefe

Depth chart: Nathan Stanley (Jr.), Peyton Mansell (rFr.), Spencer Petras (Fr.)

I'm not sure enough people realize how good Stanley could be. Don't be surprised if he is considered an upper-tier quarterback in college football by the end of the 2018 season. There's a battle for the backup job between Mansell and Petras and Iowa feels very comfortable with what it has in those two youngsters.

20. Iowa State

QB coach: Joel Gordon

Depth chart: Kyle Kempt (Sr.), Zeb Noland (Soph.), Re-al Mitchell (Fr.), Brock Purdy (Fr.)

Kempt is a former walk-on with size and ability, and the stones to beat Oklahoma in his first start last fall. When Kempt went down to injury, Noland nearly upset Oklahoma State. Mitchell brings an athletic, run-first quarterback if needed and Purdy chose Iowa State late last cycle over the likes of Texas A&M and Alabama.

21. Ole Miss

QB coach: Phil Longo

Depth chart: Jordan Ta'amu (Sr.), Matt Corral (Fr.)

Ta'amu has the ability to push Ole Miss higher on this list, but the limited depth is concerning in Oxford. Corral was a huge recruiting win for the Rebels as a four-star kid from California who has rare arm talent. He won't be ready in Year 1 though, so Ta'amu needs to stay healthy and Matt Luke needs to recruit depth quickly.

22. LSU

QB coach: Steve Ensminger

Depth chart: Joe Burrow (Jr.), Myles Brennan (Soph.), Lowell Narcisse (rFr.), Justin McMillan (Jr.)

With the arrival of Burrow, this room went from a huge question mark to a potential strength for the Tigers. Burrow doesn't bring experience to LSU, but he brings a ton of ability and he gives a young, talented depth chart time to mature. By the time Burrow is gone, Brennan will be physically prepared to take over or Narcisse will have developed enough as a passer to be effective.

23. West Virginia

QB coach: Jake Spavital and Dana Holgorsen

Depth chart: Will Grier (Sr.), Jack Allison (Soph.), Trey Lowe (Fr.)

Grier is a no-doubt talent that will be in the NFL next year. But behind him is a Miami transfer in Allison who hasn't proven much, a true freshman that plans to split time with baseball and walk-ons.

24. Missouri

QB coach: Derek Dooley

Depth chart: Drew Lock (Sr.), Micah Wilson (Soph.), Lindsey Scott (Soph.), Taylor Powell (rFr.), Jack Lowary (Jr.)

The new offensive coordinator and quarterback coach will get a lot of scrutiny this fall, but he'll shrug it off quickly because of how good one of the best QBS in the country will be. We'll see how good Dooley is after Lock is gone because behind him, there's not much.

25. Arizona

QB coach: Noel Mazzone and Kevin Sumlin

Depth chart: Khalil Tate (Jr.), Rhett Rodriguez (Soph.), K'Hari Lane (rFr.)

Tate caught the Pac-12 sleeping last season and had some mind-blowing performances, but he did sputter to the finish line a bit in his last four games of the regular season. Pac-12 defensive coordinators will be ready for him this year. There's also a very thin depth chart behind him and Arizona is in big trouble if he gets injured.
