The question already has been posed whether Randy Moss is going to command too much money after his deal expires following the 2007 season. When the Patriots acquired Moss in April, he had two years remaining on his contract and was scheduled to earn $21 million over the 2007-08 seasons. But he agreed to a restructured contract - a one-year, $2.5 million deal that included a $500,000 roster bonus and $2 million in incentives - to consummate the trade. According to the NFL's collective bargaining agreement, a player cannot renegotiate his contract more than once in a one-year period if it will cause an increase in his salary. So in Moss's case, if he hoped to sign an extension that would increase his salary, it would have to come after the season.
