But the deal never materialized into an actual offer, so the Eagles moved ahead and wound up with Sproles.
Spiller, a former standout at Clemson, was the ninth overall selection in the 2010 NFL draft.
The 26-year-old Spiller rushed for 933 yards and had another 185 yards receiving last season. He has 3,021 total yards rushing and 12 touchdowns in four seasons with the Bills.
The Eagles ultimately went with Sproles, who has the ability to run the ball, catch passes out of the backfield and return punts and kickoffs. Sproles has five career return touchdowns -- three on punts and two on kickoffs.
