NFL commissioner Roger Goodell said on Monday that the league's franchise owners might vote in May about the possibility of lengthening the regular season to 17 or 18 games per team. The issue is being discussed at the annual league meetings that began Monday morning and runs until Wednesday. "It could come as early as this May," Goodell said at a news conference. "But I think we'll have a very good sense of the ownership and our clubs as we come out of this meeting. Then we'll make a determination of when that vote is necessary. But I think it's dependent in large part on our relationship with our [television] partners and the players."
