Sproles, 31, was traded by the New Orleans Saints to the Eagles for a fifth-round draft pick in March. Sproles said he is eager to see what tricks Eagles coach Chip Kelly has up his sleeve.
"I really am," Sproles said, "because the stuff we've been doing in practice, I think it's kind of dangerous."
Sproles was primarily used as a receiving threat out of the backfield by the Saints, but said he will have a more versatile role in Kelly's offense, including more rushing attempts.
He had 220 rushing yards and two rushing touchdowns to go along with 604 receiving yards and two touchdowns last season. Sproles set the single-season record for all-purpose yards in 2011, when he amassed 2,696 yards.
The Eagles open preseason play on Friday night against the Bears in Chicago.
