According to multiple sources, some NFL owners are resisting the labor deal they've been trying to negotiate with the players. A handful of NFL owners believe the parameters of the deal being discussed don't adequately address the original issues the league wanted correct following the expiration of the last collective bargaining agreement. Some of this resistance has caused the NFL to adjust its schedule next week, moving up the time of Tuesday's meeting, with the possibility of staying until Wednesday. The league is bracing for internal negotiations. This subplot comes at a time when the NFL and NFLPA have made considerable progress, much of it on broad-picture items. The two sides, according to a source, have agreed to an unofficial timeline as to how events such as training camp and free agency would play out if there is an agreement on the more significant elements of the deal.
