The top prospects: Stanford quarterback Andrew Luck is being hailed as a once-in-a-generation prospect by many noteworthy draft analysts, including Maryland's own Mel Kiper Jr. In his three seasons at Stanford, Luck completed nearly 70 percent of his throws for 9,430 yards, 82 touchdowns and 22 interceptions. He played in a pro-style system and his intangibles are said to be off the charts, giving him the edge over Robert Griffin III. Griffin, who also ran track at Baylor, burst onto the national scene in 2011. He completed 72.4 percent of his passes for 4,293 yards and 37 touchdowns and won the Heisman Trophy. Griffin should wow scouts at the combine, but he will be hard-pressed to overtake Luck as the draft's top overall prospect. Other possible first-round picks at quarterback include Texas A&M's Ryan Tannehill and Arizona State's Brock Osweiler.
