FAYETTEVILLE, Ark. (AP) — Arkansas coach Bret Bielema wanted to get running back Chase Hayden as many carries as possible in the season opener, simply to get the freshman used to the speed of the college game. Bielema's next plan might just be to keep giving Hayden as many carries as he can handle, particularly after the 18-year-old rushed for 120 yards on 14 carries in his debut — a 49-7 victory over Florida A&M. However Bielema chooses to use Hayden moving forward, his emergence has quickly quelled any concerns about Arkansas' backfield depth following an offseason injury that ended the career of former running back Rawleigh Williams. While sophomore Devwah Whaley is still the top rushing option for the Razorbacks, Hayden and former South Carolina transfer David Williams have given Bielema plenty of running options entering Saturday's game against No.
