With his 259.16 fantasy points so far this season, fifth most among quarterbacks and a larger total than he had in any of the previous three years, Matthew Stafford has leapfrogged Larry Fitzgerald, Matt Ryan and Philip Rivers to assume the eighth overall spot. Rivers' return could shake up the leaderboard: Stafford's entry into the top 10 pushed Rivers back to 11th in scoring. With Rivers signing with the Indianapolis Colts' practice squad on Tuesday, giving him a good chance at playing for the quarterback-starved team during the season's final four weeks, he has a chance to vault back into the top 10 in place of Matt Ryan.
