It's hard to tell when Barkley will go off the board on draft day. Projected by many as the top pick following his junior season at USC, he struggled during his senior season, and as a result, his draft stock took a hit. Many project Barkley as a second-rounder, but some believe he could go in the first round, possibly to the Bills at No. 8.
This year's quarterback class isn't highly-regarded. Geno Smith is viewed as a first-round pick by most draft analysts, but some believe he'll be the only QB taken in the first 32 picks.
Barkley was excellent in his junior year with the Trojans, completing 69.1 percent of his passes for 3,528 yards, 39 touchdowns and seven interceptions. He played well last year, but his numbers weren't as good. Barkley completed 63.6 percent of his passes for 3,273 yards, 36 touchdowns and 15 interceptions in 2012.
