In some cases, they are viewed as a changing of the guard from the previous regime. With others, their name recognition and previous boss precedes anything on their resume. No matter how they arrived on campus, scrutiny for offensive and defensive coordinators is about as high as it’s ever been.

To illustrate that point, since last season only five SEC teams — Georgia, Missouri, South Carolina, Texas A&M and Vanderbilt — did not change at at least one coordinator position. And the fact that three of those teams have second-year coaches makes the dial on the pressure cooker even higher. There simply isn’t much time to make a good impression as a coordinator in the SEC.

The coaches below face heightened expectations because of a combination of player development, improving on the recent history of the program, or simply confirming that the hire was the right call.

Here are five coordinators who face the most pressure in the SEC in 2017:

Brian Daboll

Given the five-pronged attack at running back, and the reigning SEC Offensive Player of the Year at quarterback, Daboll has plenty of reasons to produce early and often for the Alabama offense. If there’s one thing in common between his current boss and former boss, Nick Saban and Bill Belichick, it’s Super Bowl and national championship success.

Because of the slew of talented coordinators who have worked for Saban and Belichick, Daboll must distinguish himself from the pack. That won’t be easy.

All eyes early on will be on his philosophical preferences, especially compared to his predecessors, Lane Kiffin and Steve Sarkisian. They each preferred to add sizzle to the attack. There’s always at least a solid minority of fans who believe a program like Alabama should just run the ball 40 to 50 times and rely on its defense. Especially given its current running back depth.

And if things go south for a period of time, the critics will bark that Daboll isn’t a former QB like Sarkisian and Kiffin. He was a safety at the University of Rochester and coached the defensive side of the ball until Belichick made him a receivers coach in 2002.

Jim Chaney

The returns after Chaney’s first season in Athens were lukewarm to a lot of fans. With the preseason hype of his coordination with offensive line coach Sam Pittman as a sort of package deal when they came to Georgia, Chaney coordinated an offense that finished 11th in the SEC in total offense and scoring in the SEC in 2016.

Georgia's 24.5 points per game ranked 102nd nationally and were fewer than any of Mark Richt's 15 Bulldogs teams.

That makes the development of sophomore quarterback Jacob Eason squarely on Chaney’s shoulders.

The chants of “Run the ball, Bobo,” might still echo in Sanford Stadium from a fan base that had portions critical of Mike Bobo when the team averaged more than 30 points per game. The peanut gallery could set its sights on Chaney if the offense doesn’t deliver early.

Last season Georgia was 87th in offense nationally and 102nd in scoring offense. That’s part of the reason Chaney traveled the country in the offseason to look at college and NFL teams in order to help the Georgia offense.

Given the upgraded offensive line, thanks to Pittman, and a host of young receivers to go with the talented backfield, much will be expected of Chaney.

Kurt Roper

In a similar situation as Chaney, Roper, the South Carolina offensive coordinator, has a bunch of weapons that at times looked strong in 2016 but ultimately struggled.

On one hand, Roper coached a unit that had a host of accolades from quarterback to running back. On the other hand, he couldn’t kickstart the original unit, which led to the midseason changes. The Gamecocks were last in the SEC and 116th in the nation in scoring last season at 20.8 points per game. What might happen at this year’s bye week if production is missing?

There was plenty of reason for optimism, most notably the Birmingham Bowl scoring outburst of 39 points and 481 yards in a loss to South Florida. Along with Jake Bentley, the Gamecocks return their top two rushers and top six receivers, and many wonder how Roper will lead them to the next step.

Paul Rhoads

The former Iowa State coach is being asked to turn around an Arkansas defense that has slipped since 2014 when it was fourth in the SEC in points allowed, at 19.2 per game.

Last year, the Razorbacks gave up 31.1 points per game.

The internal promotion brings a positive after Rhoads’ defensive backs unit forced 10 interceptions and returned four for touchdowns. That is the most one season for the program since at least 1985.

Rushing defense is one area Rhoads must plug, and he plans to do it by switching to a 3-4 alignment with five returning starters. His previous stint in the SEC, at Auburn under Tommy Tuberville, Rhoads’ defense in 2008 ranked 18th nationally in scoring, allowed 18.0 points per game and 178.8 yards passing, which was No. 22nd nationally.

With plenty of new faces on defense, and the new alignment, how much patience will fans have for a unit that has struggled mightily for a few years?

Matt Canada

Beating the eventual national champion goes a long way as a resume builder. But new LSU coordinator Matt Canada hopes Pittsburgh’s win over Clemson last season is just a footnote in his career leading to his LSU tenure.

That caught Ed Orgeron’s eye along with the 41 points per game average. Because Canada can coach both styles of quarterbacks, which LSU has, his coaching versatility should be on full display.

Canada’s expected to deliver a different twist to the LSU offense that previously relied on one or two players almost exclusively. In short, distribution of the ball will be all over the field, and more players will get their hands on the ball in more ways. With presumably more talent than he had at the likes of Pittsburgh, N.C. State, Northern Illinois and Indiana, will that be enough to put the Tigers over the top in the SEC West?
