Purdue by quarter

Expected points the running game added PER PLAY that quarter. Zero is a neutral carry; around +0.15 is a strong quarter on the ground and −0.15 a poor one. ⚠ It is an average, so a three-carry quarter counts the same as a twenty-carry one — read the bars with the score in mind.

One row per game, through the season · one scale across every row · · = no plays that quarter, which is not a zero

The same measure for throws. Passing swings harder than rushing in both directions, so its bars are taller either way — compare a passing quarter to other PASSING quarters, not to the running grid above.

Both together, weighted by how often each was called — so this is closer to the scoreboard than to either grid above it, and a quarter can be positive here while one phase was losing ground.

How BIG the good plays were — average points added counting only the plays that worked. It says nothing about how often they came, so a quarter of one long touchdown and nine three-and-outs scores well here and badly on success rate.

Share of plays that stayed on schedule: half the yards needed on first down, 70% on second, all of them on third or fourth. Around 45% is an average offense. This is the FREQUENCY half of the pair above — explosiveness is the size half.
