McShay's updated Top 32: Ranking 2018 NFL draft prospects

McShay says Barkley is most dynamic weapon in draft (1:14)

Todd McShay breaks down his top four prospects for the 2018 NFL draft, including dynamic running back Saquon Barkley of Penn State. (1:14)

With at least four games under most teams' belts, let's take a look at how the top 32 prospects in the nation are performing. This board isn't that different from the previous version two weeks ago, but a new quarterback joins, along with a rise for the best running back in college football.

Here are my top prospects for the 2018 NFL draft right now:

Note: Underclassmen are marked with an asterisk.

1. Sam Darnold, QB, USC*

Grade: 95 | Previous rank: 1

Darnold has made some questionable decisions throwing the football this season (at least one interception in each game so far), but it hasn't changed my evaluation of him. His delivery still needs to be cleaned up, but his accuracy is phenomenal. He is the most complete quarterback in college football and a potential franchise signal-caller.
