With about three weeks to go until the 2018 NFL Draft, here are my latest top-50 prospect rankings. Penn State RB Saquon Barkley remains the No. 1 player on my board. There's movement up and down the rankings, but the biggest movers are in the second half of the top 50. The movement here is based on a combination of NFL Scouting Combine results, pro-day results, further film review and feedback I've heard about teams' interviews with prospects. Guys like Maryland WR D.J. Moore have aced the offseason, and that's why they're moving up.
Falling out: Pitt OT Brian O'Neill (45), Nevada OG Austin Corbett (48), Fort Hays State DT Nathan Shepherd (50).
