I read Seth’s post today and spent this morning running through the every snap video uploaded by DGDestroys. The RPS nature of that one play made me question my harsh take on the OL performance in that game.
This play is well blocked… it just doesn’t comprehend the safety.
Good point Seth. Good job OL. Maybe there are more RPS losses than OL misses in this game (I thought to myself…)
So I downloaded the Game stats for the year; adjusted the rushing output for line yards following for the most part Football Outsiders technique to decipher how much the OL contributed to the rushing stats so far. Hit the link above for the run down on Adjusted Line Yards but here is the short story.
…the Adjusted Line Yards formula takes all running back carries and assigns responsibility to the offensive line based on the following percentages:
Losses: 120% value
0-4 Yards: 100% value
5-10 Yards: 50% value
11+ Yards: 0% value
I started to normalize and pull the RB yards – but it’s not what this morning is going to be for me. Instead I thought I’d post this the rough run down because I need to go and get MSS chores done.
The concept here is that yards over 10 are due to shake and bake and WR blocking while <10 yards are more or less on the OL. A good RB skews this up… a bad one down but the idea is in general a good one.
Stats are from http://www.cfbstats.com/. It looks like sacks are counted as rushing attempts. I didn’t doctor this data – it’s straight from their rushing chart. I could tinker with this but I’m not sure how much value it would add. The comparison is straight up.
Ohio is a significant shift in OL performance in terms of Line Yards.
It’s difficult to pull out OL stats. The play that Seth pulled this morning is comprehended in the Stat pull and analysis I did just now as an OL miss – but it wasn’t as I take his analysis. In general, I think the Adjusted Line Yard stat is a good one though to begin to tease this out.
I have intentions of looking at this further (Power Success/RB Yard/2nd Level Yards/Sacks and Sack Rates) with comparisons by and to conference and by coaches… but I’m not sure I will get back to this. In the meantime I think it’s worthy to share this season run down.
