The Los Angeles Rams saw a ton of success in the 1990s and early 2000s led by head coaches Dick Vermeil and Mike Martz. However, those aren't the only successful coaches that the franchise has employed throughout the years.

Even right now, Los Angeles has Sean McVay entering his fourth season with the Rams, and he's seen plenty of success thus far. While he hasn't been with the organization for a lengthy period of time, McVay is proving to be a long-term coach for the Rams.

As Los Angeles prepares to enter their 84th season as a franchise in the NFL, they've had 27 head coaches in their team's history. Without wasting any more time, here are the Rams' five best head coaches of all time.

5. George Allen

From 1956-1965, the Rams didn't see much success, winning just 43 games in those 10 seasons. Then, with the arrival of George Allen as head coach in 1966, Los Angeles suddenly saw a seismic shift in the win column.

Altogether, Allen would coach the Rams from 1966-1970 and would lead the team to an impressive 49-17-4 record. During his five-year tenure, Los Angeles would make the playoffs twice, but fail to win a single postseason contest.

Still, Allen's .742 win percentage is the most by a Rams head coach that coached in more than 25 games. As a result, he cracks the list of best coaches that the Rams have had over the years.

4. Chuck Knox

Not long after Allen was let go by the Rams, Los Angeles found a viable replacement in Chuck Knox in 1973. Knox would have two stints with the Rams, with his first time with the team spanning from 1973-1977.

Just in his first five seasons, Knox was able to lead Los Angeles to a 54-15-1 record. While winning 10 or more games in his first five seasons, Knox also led the Rams to three playoff victories in his five seasons.

Following his first stint with the organization, Knox rejoined the Rams from 1992-1994. Unlike the first time he coached the Rams, Knox didn't provide fruitful results, posting a dismal 15-33 record.

3. Sean McVay

Prior to the 2017 season, the Rams were coming off of an awful era under head coach Jeff Fisher. In his five-year tenure with St. Louis-Los Angeles from 2012-2016, Fisher put together a putrid 31-45-1 record.

Luckily for the Rams, they chose to hire McVay to replace him in 2017, and it's safe to say they hit a home run in their selection. Over his first three years, McVay has recorded a 33-15 record, leading the Rams to a Super Bowl appearance in 2018.

While he failed to deliver Los Angeles a Super Bowl victory, McVay is still young and has plenty of room for improvement. Even though he's been with the team for just three years, it's evident that McVay could carve out a long, prosperous career with the Rams.

2. Mike Martz

In the early 2000s, the Rams were beginning to move on from “The Greatest Show on Turf” offense. After securing the franchise's lone Super Bowl in 1999, St. Louis continued to sport one of the best offenses in the NFL under Mike Martz.

Martz, who was the offensive coordinator of the Rams in 1999, was promoted to head coach the following season. The offensive-minded coach would spend five seasons with the organization before being fired during the 2005 season.

Before everything fell apart in 2005, Martz led the Rams to four playoff appearances in five years. Despite making a Super Bowl in 2001, Martz and the Rams became the first of six teams to lose to the New England Patriots in the Super Bowl.

1. Dick Vermeil

Last but not least, there's no surprise that Dick Vermeil is No. 1 on the list of the franchise's head coaches of all time. When you're the only coach to secure a Super Bowl in franchise history, you have a decent case to be the best coach for that organization.

Once again, in 1999, the team deployed one of the best offenses in NFL history nicknamed the “Greatest Show on Turf.” With Kurt Warner under center, the offense also featured Marshall Faulk, Isaac Bruce, Torry Holt, and Orlando Pace protecting Warner's blindside.

Given the offense they had, plus a solid defense, the Rams defeated the Tennessee Titans — who Fisher coached in 1999 — to win their first Super Bowl. Even though he lasted just three years with the organization, Vermeil will always be celebrated in Rams' storied history.
