The Rams had 2 penalties that extended the Lions' drive (on third down), including another one on 4th down on one of Detroit's touchdowns that was declined. Had they
not scored, they would have had another opportunity anyway.
They also had 2 penalties that stalled their own drive, both of which happened deep in their own territory, back-to-back, that turned a 3rd & 5 into a 3rd & 15. And
that drive started on their own 10 as a result of a holding penalty on Benny's 30 yard kickoff return.
But I get what he's saying anyway. Penalties (in and of themselves) don't typically equate to a disproportionate amount of losses for the team that commits them. Last year Carolina had 7 fewer penalties on the year. The year before that, the Broncos and Rams had the same amount and Seattle led the league with 23 more. But all that said, this team doesn't the the weaponry to overcome them like those other teams if they come at inopportune times like described above.
