Kiper's Big Board for 2019 NFL draft: Ranking top 25 prospects

SEC pass-rushers and a quarterback are moving up. Another quarterback is moving down. Three new prospects are in the top 25.

My updated Big Board for the 2019 NFL draft -- the best prospects for this class -- is below.

A few notes before I get started, same as always:

  • These aren't detailed scouting reports. I still have a lot of work to do on these prospects, and what they do from now until January matters a lot.

  • The draft is all about projection, so keep in mind that several guys here have started only one season.

  • Height and weight are based on what we have from schools. We don't get official numbers until the 2019 combine.

Note: One asterisk denotes the player is a junior, and two asterisks denote the player is a redshirt sophomore in 2018.

1. Nick Bosa, DE, Ohio State*

Height: 6-foot-4 | Weight: 263 pounds | Previously: 1

I don't expect Bosa's core muscle injury to affect his draft stock, even after it was announced that he isn't returning to Ohio State and will instead begin preparations for the draft. It's not an injury with lasting long-term effects. The Buckeyes' defensive line isn't the same without him. He's the Class of 2019's best edge rusher, and it's not close. He is advanced for his age in his technique -- you can probably thank his brother, Joey, and dad, John, both former first-round picks -- and he hasn't put up huge numbers because of Ohio State's talented defensive line rotation. He has four sacks in the three games after picking up eight in 2017.
