Oklahoma State's Justin Blackmon is the top wide receiver in the draft, and he could go as early as No. 2 overall to the St. Louis Rams, who need help at wide receiver. Blackmon caught 121 passes for 1,522 yards and 18 touchdowns in 2011. Notre Dame’s Michael Floyd has size (he’s 6-foot-3) and speed. Baylor’s Kendall Wright is a burner. And South Carolina’s Alshon Jeffery, who has been linked to the Ravens in mock drafts, could also be a first-round pick, but his 40-yard dash will be scrutinized at the scouting combine.
