I think some context is in order on those numbers, which you seem to be using as ammunition to diminish Faulk's production...

Marshall Faulk, Indianapolis Colts (1994–1998)
Faulk was drafted in the first round with the second overall pick in the 1994 NFL Draft by the Indianapolis Colts, who were in desperate need of a running game. On July 25, 1994, Faulk signed a seven-year $17.2 million contract and received a $5.1 million signing bonus. Faulk responded by rushing for 1,282 yards, 11 touchdowns, and one receiving touchdown. The Colts improved to 8–8. Marshall Faulk, later that season, would become the first NFL player to win both the Offensive Rookie of the Year Award and the Pro Bowl's Most Valuable Player Award in the same season. He was also the first rookie to win Pro Bowl MVP.
The next season Faulk rushed for 1,078 yards and 14 total touchdowns. The Colts made the postseason, going 9–7, and narrowly missed the Super Bowl after a close loss to the Pittsburgh Steelers in the AFC Championship Game, which Faulk missed due to a nagging toe injury.
The next year was a miserable one for Faulk. Because of a toe injury he suffered earlier in the season, he rushed for only 587 yards, with a 3 yards-per-carry average. He led the Colts in yards from scrimmage with 1,015. He recovered from the injury and rushed for 1,000+ yards in each of the next two seasons, setting a new personal high with 1,319 in 1998. He also caught 86 passes for 906 yards that year (playing alongside rookie quarterback Peyton Manning) and was the NFL's leader in total yards from scrimmage with 2,227, beating out Denver's MVP running back Terrell Davis by 2 yards, while also finishing 4th in the league in receptions. It would also be the first of an NFL-record 4 consecutive 2,000+ total-yard seasons.

By any measure, that is an exceptional 4 year start to his career.
Having said that, I too love what Kyren Williams brings to the table. Love his vision, his quickness, his ability to create holes when none are there, his toughness and his character. Just a fantastic find and kudos to the Rams for getting him.
