As a freshman in 2005, Gilyard played cornerback. In 2006, he was redshirted for academic reasons.
In 2007, he was moved to receiver where he caught 36 balls for 536 yards.
2008 is when he really began to shine. He caught 81 balls for 1,276 yards and 11 touchdowns.
To prove that wasn't a fluke, he posted nearly identical stats in 2009.
The biggest question mark on him that I've read is whether his light frame can effectively shed defenders at the NFL level. In the Bearcats bowl game, he caught seven balls for 41 yards and had trouble getting away from the Gators defensive backs.
He's also a kick returner. The Chiefs, of course, rotated out receivers and kick returners all season.
NFLDraftScout.com ranks him as the 11th receiver in this draft class and lists him at 5'11 and 179 pounds.
