The most experienced wide receiver on the team, Billings caught 24 passes for 277 yards in 11 starts last fall. After seeing reserve duty in 2006 when he caught three passes for 47 yards, he grabbed 28 balls for 321 yards and a TD in 2007.
Billings attended spring practices this year, but was not allowed to participate due to academic reasons, Chizik said.
