The Tennessee Titans have hired San Francisco 49ers director of player personnel Ran Carthon as the team's new general manager, according to multiple reports.

Carthon, 41, has spent 15 years as a scout or executive in an NFL front office following a short on-field career, including the last six in San Francisco.

The Titans' new GM has connections to Jeff Fisher and got his scouting start under a former Patriots executive but has spent the last six seasons with one of the best front offices in football.

Here's what you should know about Carthon:

Former Florida star RB became a scout under Thomas Dimitroff in Atlanta

Carthon, the son of former NFL fullback and assistant coach Maurice Carthon, led Florida in rushing his senior college season but was an undrafted free agent running back signed by the Colts in 2004. After the three seasons as either a practice squad player or a reserve in Indianapolis (earning a Super Bowl ring in 2006), Carthon retired following the 2006 season after a stint on the Lions practice squad.

Carthon got back into football in 2008 as a pro scout in the Falcons front office, a role he held for four seasons under new Falcons GM Thomas Dimitroff.

Dimitroff took the Falcons' GM after spending five years as the Patriots' college scouting director.

Got his big break in the front office with Jeff Fisher-era Rams

Carthon got his first substantial promotion into a front office executive role in 2012, following Les Snead from Atlanta to the St. Louis Rams. Snead, the team's new GM in 2012, hired Carthon as the franchise's director of pro personnel, a role he held for five seasons.

The front office changes occurred after the Rams hired former Titans coach Jeff Fisher as the team's head coach. Fisher took a season off after being fired by the Titans after 16 seasons.

Carthon led the pro personnel department for five seasons and helped create a roster that eventually was inherited by Sean McVay after Fisher's exit late in the 2016 season. In that time, the Rams drafted Aaron Donald, Jared Goff and Cooper Kupp, among others, and acquired Andrew Whitworth and Robert Woods via free agency.

A budding star in 49ers organization

The 49ers hired Carthon after the 2017 draft as the team's director of pro personnel as GM John Lynch molded the front office in his first season.

Carthon was the team's pro personnel director until 2020, when he was promoted to director of player personnel.

According to the team's biography of Carthon, he "is responsible for evaluating the top college prospects and assists in the construction of the pro free agency board and evaluations. He also works with the football administration staff with player market analysis and unrestricted free agency strategy."

San Francisco's current roster may be the deepest and most balanced in the league.

While the 49ers have made some high-profile and high-value trades since Lynch and Carthon have been in the front office — Jimmy Garoppolo from New England in 2017, Trent Williams from Washington in 2020 and Christian McCaffrey from Carolina this season — their roster has benefitted from some strong drafting, especially in Days 2 and 3.

In 2017, the 49ers selected George Kittle in the fifth round, lessening the impact of missing on a pair of first-round picks (Solomon Thomas and Reuben Foster). In 2018, San Francisco picked Fred Warner in the third round. A year later, the 49ers picked Nick Bosa No. 2 overall, Deebo Samuel in the second round and Dre Greenlaw in the fifth round. In 2020, the Niners selected Brandon Aiyuk with their second first-round pick. And in 2021, San Francisco selected Talanoa Hufanga in the fifth round. All seven players are key parts of a team seeking its third trip to the NFC Championship Game in four years.

The 49ers also drafted QB Brock Purdy with the final pick in last April's draft, which has worked wonders. Purdy replaced the injured \Garoppolo in December and is 6-0, including last weekend's 332-yard, three-touchdown performance in his playoff debut against Seattle in the NFC Wild Card round.
