NFL commissioner Roger Goodell called proposals from St. Louis, Oakland and San Diego to keep their teams "unsatisfactory and inadequate" ahead of an owners vote this week on the relocation issue.
The Los Angeles Times reported Saturday that a 48-page document was sent to all NFL teams a few days before a decision could be made to approve the move of one or more franchises to Los Angeles.
Goodell said each city "did not develop their proposals sufficiently to ensure the retention of its NFL team," but he did not make any recommendations on which teams should be moved or which of two stadium projects to accept.
The six-member Committee on L.A. Opportunities is expected to make a recommendation after the league's owners meetings on Tuesday and Wednesday in Houston. At least 24 of 32 votes will be needed for approval to move a team or teams to Los Angeles for the first time in 20 years. The league could also delay the relocation vote for a year.
The Chargers, Rams and Raiders all applied for relocation on Monday.
The Chargers and Raiders are aligned with a $1.7 billion stadium project in Carson, Calif. The Rams, who played in Los Angeles from 1946 to 1994, are behind a $1.86 million stadium in Inglewood that team owner Stan Kroenke plans to build.
The Dallas Cowboys proposed an alternative plan on Friday for the Rams and Chargers to play in the Inglewood stadium, according to reports.
The St. Louis stadium task force took issue with Goodell's assessment of the cities trying to retain their franchises.
"We have not seen the report, nor do we expect to, as that would be a matter between the league office and team owners," it said in a statement. "We do hope the NFL will communicate with all home markets as to their status prior to any decisions next week, particularly here in St. Louis where so many people have dedicated themselves over the past 14 months to producing a strong and certain stadium proposal for the NFL and our hometown Rams."
