Georgia Tech Offensive Production and Downs

Noon execution.  (Photo by Streeter Lecka/Getty Images)

The biggest change I noticed when watching the Kansas and UNC games was that GT was executing on 1st down with greater efficiency against North Carolina. And I hadn't really thought of a good way to display this visually until today. Here's a breakdown of play results by down for each 1st, 2nd, 3rd, and 4th down against Kansas and UNC:

Offense_medium

Against UNC, 61% of GT's 1st down plays were either 1st downs, touchdowns, or on pace for a first down (>3 yards per play). Against Kansas, this number was only 47%. This translates to an average of 2nd down and 7.5 yards to go against Kansas and a more manageable 2nd down and 6.3 yards to go against UNC. The difference is numerically minute but in playcalling the difference is huge. One offense is on pace for constant three and outs while the other is on pace for consistent 1st down conversions.

One thing I saw

The plays up the middle (B-Back) were much more successful in the UNC game than in the Kansas game. That helps get 3-4 yards on every play without having to risk getting the ball on the perimeter.

Also, the options in your stacked bar chart aren’t exclusive. For instance, what if, on 3rd and 2, we gained three yards and got a first down? How were those instances handled?

That would fall under the gold “First Down” category.

I know they’re not mutually exclusive. I was mostly targeting first downs. I should’ve put together a more complex stratification (e.g. TD, T/O, 1st Down, On Pace for a First Down, Off Pace for a First Down) rather than yards gained.

How you did it was fine

I was just wondering which category something like that would fit into.
