A year ago, Stan Kroenke's Los Angeles Rams didn't even crack the top 50 in Forbes' annual list of the world's most valuable sports franchises.

But the Rams' rocketed up to No. 12 in this year's rankings, published Wednesday by Forbes, making them the biggest risers on the list.

The Rams are worth $2.9 billion according to the Forbes, double the $1.45 billion value of the team in 2016. The '16 value of the team had not yet factored in the move to Los Angeles, according to Forbes.

In 1995, Kroenke's original 40 percent stake in the team cost $80 million. So even before the move to LA, he made a lot of money in St. Louis.

This year, the Rams are nudged between the No. 11 Washington Redskins ($2.95 billion) and the No. 13 (tied) New York Jets and Los Angeles Dodgers ($2.75 billion apiece).

All told, 29 of the 32 NFL teams made the top 50 with the Rams ranking as the sixth-most valuable NFL franchise behind No. 1 Dallas ($4.2 billion), No. 6 New England ($3.4 billion), No. 8 New York Giants ($3.1 billion), No. 9 (tied) San Francisco ($3 billion), and No. 11 Washington.

The entire NFL benefited from the relocation of the St. Louis Rams and San Diego Chargers to LA, and the eventual move of the Oakland Raiders to Las Vegas. According to ESPN, the 29 league teams that did not relocate will each pocket $55 million over 11 years in relocation fees.

That bounty explains some of the increased value for NFL teams in this year's Forbes rankings.

The Rams and Chargers do not get a share of their LA relocation fees, but do receive a share of the Raiders' relocation fee. Similarly, the Raiders do not receive a share of their relocation fee, but do get a share of the Rams' and Chargers fees.

The Cowboys are ranked No. 1 by Forbes for the second consecutive year. Previously only soccer teams had been in the top spot, with either Manchester United and Real Madrid ranked No. 1 in the first five years since the rankings began in 2011.

Kroenke double-dipped in this year's top 50, with his Arsenal soccer team of the English Premier League ranked No. 43 — down 20 spots after dropping in value from $2 billion in 2016 to $1.93 billion in 2017.

The value of the St. Louis Cardinals baseball team rose 12 percent in 2017 — to $1.8 billion from $1.6 billion last year — but the Cardinals dropped to a tie for No. 47 (with Brooklyn of the NBA and New Orleans of the NFL) from No. 38 in 2016.

According to Forbes, the Cardinals are the seventh-most valuable baseball franchise, trailing the No. 2 New York Yankees ($3.7 billion), No. 13 (tied) Dodgers, No. 16 (tied) Boston ($2.7 billion), No. 18 Chicago Cubs ($2.68 billion), No. 19 San Francisco ($2.65 billion), and No. 39 New York Mets ($2 billion).
