A ray of sunshine in NFL labor talks?

There is talk that there might be an extension of deadline for the NFL and the players' association to cut a deal. According to multiple sources on Twitter and Adam Schefter speaking on SportsCenter just a few minutes ago, the two sides are discussing pushing back the start of the league year in order to give some more time to work out a new collective bargaining agreement. Don Banks of Sports Illustrated quoted a source who said that the extension talks are "legit but fragile". The fact that an extension is being discussed implies that there is some progress being made in the talks. If there wasn't some give and take going on, which has been notably lacking to date, there would be no reason to to extend the agreement. An offer by the owners to show some financial information may have been the impetus to getting the two sides to talk about extending the deadline. Apparently, the owners have offered the extension and the players are considering it. Multiple extensions were agreed to in 2006, the last time the CBA was being negotiated. The eventually did get an agreement.
