He absolutely did in 2015.
(10/17): Registered eight total tackles...Recorded 3.5 tackles for loss to mark the fifth time this season he posted 2.0 or more TFLs in a game...Collected 1.5 sacks for his fourth multi-sack game...Helped the Penn State defense accumulate 10.0 tackles for loss...The 10.0 tackles for loss were the most surrendered by Ohio State in 2015
And then defensive end Garrett sickels (who?) the year penn state beat ohio state in '16 had 3.5 sacks. Most of them coming against the same guy that willekes beat today (Isaiah Prince). I don't even know if that sickels guy is in the NFL.
(Edit he plays for the Rams but guess what the Browns did have him on the roster in 2017.)
Point being there have been plenty of guys that have dominated the Ohio State offensive line that haven't turned into Khalil Mack.
Willekes like nassib started out as walkon.
