According to sportsfacts.org (nice name), these are the players who led the NFL in penalties at their position:
Cross-checking with NFLPenalties.com, these seem to be mostly accurate.
First looking at the offensive tackle positions, I found that Bradley Sowell and George Fant each had seven. Ereck Flowers had 13, Taylor Lewan had 12. But NFLPenalties also lists the Bucs’ Donovan Smith also with 13 penalties. Part of the discrepancy here will be if the penalties were declined or offsetting.
