Matthew Stafford will become the highest-paid player in NFL history with the five-year deal he has agreed to with the Detroit Lions, sources told ESPN on Monday night. The deal will have an average annual value of $27 million, a source said, putting Stafford ahead of the five-year contract that pays $25 million annually to Oakland Raiders quarterback Derek Carr, which Carr signed last month. A source told ESPN's Adam Schefter that Stafford's deal is expected to guarantee him a record $92 million, including a $50 million signing bonus. The previous record for guaranteed money issued to an NFL player was $87 million for Andrew Luck of the Indianapolis Colts. read more http://www.espn.com/nfl/story/_/id/...ford-detroit-lions-agree-historic-5-year-deal
