I watched the Interior D-Lineman drills. Most of the known studs checked out both in their measurements and their drills.

To be specific, these players looked like the real deal to me:

Andrew Billings - Very impressive quickness and power.
Joey Bosa - The Energizer Bunny. Versatile.
DeForest Buckner - Made everything look easy.
Jonathan Bullard - Fast, quick, and strong. May be a 4-3 guy at 285 pounds.
Kenny Clark - Great in drills.
Robert Nkemdiche - Amazing athlete at 294 pounds.
Sheldon Rankins - Runs well, very quick with great balance, and strong.
Jarran Reed - Top notch athlete.
A'Shawn Robinson - Same as Reed. Does Alabama have a 3-D printer for D-Lineman?

That makes 9 D-Linemen who could be 1st Round picks, IMHO.

Interior Linemen whose numbers and/or drills disappointed:

Austin Johnson
Adolphus Washington

Interior Linemen who surprised in a good way:

Sheldon Day - Very quick and runs well.
Javon Hargrave - Big, strong, fast, and worked out well. From South Carolina State!
Willie Henry - Has all the measureables and worked out well.
Matt Ioannidis - Big, very strong, and very athletic.
Hassan Ridgeway - Good drills, showed real power.
Jihad Ward - Looked very good in drills. Tall with long arms.
