A newspaper says contractors have submitted roughly $800,000 in bills toward the development of a new Saint Louis football stadium that’s still tentative.  The Saint Louis Post-Dispatch reports two executives with the agency that owns and operates the Edward Jones Dome, the Rams’ current home, have authorized the hiring of or payments to more than a dozen firms involved in the project.  The newspaper says those executives have signed architects, engineers, surveyors, planners, contract attorneys, tax attorneys and bond attorneys to contracts totaling at least $40 million.  Members of the Saint Louis stadium task force last week made their case to NFL officials, hoping to keep the Rams in Saint Louis or attract another team if owner Stan Kroenke moves the franchise to Los Angeles.
