Vanderbilt’s offense produced almost no big plays. That’s not going to work when you can’t produce small plays, either.
(Quick explainer: PPP is points per play. “Success,” in efficiency terms, is defined as gaining 50% of the needed yardage on first down, 70% on second down, and 100% on third or fourth down. PP40 is points per trip inside the opposing 40-yard line, and is a measure of finishing drives.)
Here’s a longer explanation of the Five Factors from SBN’s Bill C. if you’re really interested. Bill uses IsoPPP to calculate explosiveness, which I don’t have the time or energy to calculate, but as a general rule the Five Factors correlate pretty strongly with winning football games.
