Failed sportsbook operations BetBones (SBR rating F) pumps out two more new sportsbooks for the 2007 NFL season. PremiumBettor & UBetAndWin both enter the SBR rating guide with an F rating. The operation has proven to be insolvent and has stiffed it's staff members at the end of 2006. At that time the sportsbook blamed a lack of investor funding. The sportsbook is now serving as a turnkey service which partners with small webmasters to build fly-by-night sportsbooks. Five of seven BetBones-related sportsbooks are now off-line.
