19. Keenan Allen, San Diego Chargers
One of the beneficiaries of Philip Rivers’ career renaissance in 2013, Allen had a breakout rookie season, eclipsing the thousand-yard mark with 71 catches and eight touchdowns. He did that largely on intermediate routes, but that could change in 2014, as Allen reportedly arrived in camp bigger and faster, and has been blowing by DBs in scrimmage. He’s got great body control and already moves faster than his pedestrian 40 time suggested. He could be in for a true breakout year in his second season. (Justin Edmonds/Getty Photo)
