The Chargers looked completely unprepared in the second half against the Broncos, and the Chargers' poor execution led to them getting overwhelmed in every phase of the game.
The Broncos made effective adjustments at halftime to keep the Chargers on their heels. Turner did nothing to combat the Broncos' adjustments, and he sat by idly as Philip Rivers continued to make deep drops in the pocket and reel off ill-advised throw after ill-advised throw.
Rivers should shoulder much of the blame for Monday's loss, but Turner deserves to be lambasted as well.
Following the loss, Turner said, “If you want to make this about somebody. It's not about one of the guys in there. Make it about me.”
Chargers' fans wanted Turner gone after yet another disappointing season in 2011, but Dean Spanos retained Turner to maintain continuity on an aging team.
There's no doubt that Turner is once again on the hot seat, and the only thing that will get him off is if he can manage to win the AFC West and go deep into the playoffs.
It's still early in the season, so any team is capable of finishing the season strong.
However, Chargers' fans have little confidence in Turner due to his past mistakes.
Therefore, it might be time to take a look at the potential candidates that could replace Turner down the road.
Let's take a look at four coaches that might fit in well in San Diego.
Bill Cowher's name has been bandied about among Chargers' fans ever since Marty Schottenheimer was let go.
Cowher as the head coach in San Diego may seem like a pipe dream at this point, but there's no doubt that installing him as the head coach would instill discipline into the perpetually disappointing squad.
If the Chargers can somehow get Cowher to listen to their pleas for help, he would likely want to run the whole show in San Diego.
This means that A.J. Smith would have to be removed from the organization, and that should be no problem for a team that has gone nowhere the past few seasons.
When Pete Carroll replace Jim Mora Jr. as the head coach of the Seattle Seahawks, he only retained two members from Mora's staff—Gus Bradley was one of them.
Bradley has made Carroll look like a genius.
He has shown the ability to make his personnel perform to the best of their ability, and he is constantly throwing exotic looks at opposing offenses.
Bradley is extremely creative, and he has helped turn many of his previously unheralded defensive players into stars.
He is the polar opposite of Turner, and he is exactly what the Chargers need.
In a YouTube video, Brock Huard said, "I left it [an interview with Bradley] thinking this guy's going to be a head coach."
Huard's timetable for Bradley becoming a head coach is in the next three to five years, but Seattle's defensive performance in 2012 will likely have NFL teams knocking on Bradley's door during the offseason.
Jon Gruden is similar to Cowher in that Chargers' fans have been dreaming about him becoming their coach for many years.
Gruden recently signed an extension with ESPN, but a team could potentially coax the former coach back into the NFL if they present him with the right situation.
In an interview with the Los Angeles Times, Gruden said, "Being out of coaching, you miss the game, you miss the players terribly."
To clarify, Gruden goes on to state that he loves doing Monday Night Football, so a return to coaching is not exactly inevitable.
As the color commentator for Monday Night Football, Gruden was a firsthand witness to the Chargers wilting under pressure. He is forced to study teams for ESPN, and he should know exactly how to fix the Chargers.
As far as fit goes, Gruden would be perfect for the Chargers. He is a skilled offensive mind, and he ensures that his team is disciplined.
If the Chargers cannot persuade Gruden to come out of the press box, a fine alternative could be special teams coach Rich Bisaccia.
Bisaccia is a former assistant head coach of Gruden's while on the Tampa Bay Buccaneers coaching staff.
Last year, Gruden said, "“He’s a tremendous football coach, great with players, smart, works his butt off. I’d hire him as a head coach. If I was in position to interview people and look for quality candidates and he’s certainly one of the best I’ve been around.”
Bisaccia has a fiery personality, and he was instrumental in turning around a Chargers' special teams unit that was the laughingstock of the NFL.
A jump from special teams coach to head coach would be a large one, but John Harbaugh made a similar one when he became the head coach of the Baltimore Ravens.
If Turner is let go during the season, it would be smart to give Bisaccia a trial run as the head coach.
