Alex Hornibrook's entire offense went on to the NFL.
RB: Jonathan Taylor, Corey Clement, Dare Ogunbowale
FB: Alec Ingold
TE: Troy Fumagalli, Jake Ferguson
WR: Quintez Cephus, Kendrick Pryor
OL: Tyler Biadasz, Michael Dieter, Ryan Ramczyck, David Edwards, Cole Van Lanen, Beau Benzschawel, Logan Bruss (Tyler Beach was in camp with the Steelers this year and the Texans last year)
Surround Locke with that talent and he'd look a lot better. I don't know if there's one offensive skill position player on the current team who will go on to the NFL, much less eight.
