Money may not be the main point of contention between the NFL and the NFLPA as they work towards a new collective bargaining agreement. The request by owners that about $2 billion of total revenues be deducted before they split the rest with the players has been a sticking point ever since 2008. That's when the owners opted out of the current collective bargaining agreement, which would have expired last Thursday if not for two extensions. The deadline now is at the end of Friday, and a compromise on that figure? the owners already deduct about $1 billion for operating expenses from the $9 billion overall take?might be easier than reaching accord on expanding the regular season to 18 games or several other issues. "We have made player safety our biggest concern, and we won't back off on that," said Titans guard and player representative Jake Scott.
