Hoke was top notch at this aspect of his job.

Via Friend of the Blog Craig Ross, offensive and defensive red zone efficiency in last year's Big Ten:
- Opp = number of redzone opportunities.
- FGM = made field goals.
- Poss Pts = possible points
- RZEff = Pts / Poss Pots
- Trad = The traditional, stupid way of calculating red zone efficiency: (TD + FGM) / Opp.
Note how dumb the traditional measures of redzone efficiency can be: Michigan State finished ninth in the league in points gained as a percentage of the maximum and third by traditional measures.
It doesn't matter which metric you use, though: Michigan is thunderously last in this category. That's not a huge surprise when you're as turnover-plagued as Michigan was. Add on the First And Goal Of Doom against Illinois and there you go.
No surprises here. Defensive red zone efficiency seems much better correlated with overall performance than the offensive variety, Illinis respectability nonwithstanding. Michigan isn't last by a mile this time, but they're not far off the bottom. No fancy explanations needed here: the defense sucked anywhere on the field last year.
Just start screaming now. It will save time. PPT is "points per trip," and it hates you:
On average, Michigan gave up 2 more points per redzone trip than they got. Over the course of the season this cost them 122(!!!) points relative to the opposition.
I don't have any idea how much year-to-year correlation there is in this stat, but if I had to guess I'd say there was a moderate amount. It's not as loopy as turnover margin, certainly—Wisconsin's always going to be good inside the five—but I bet crazy numbers like Michigan's have a tendency to head for average the next year. Let's hope so, anyway.
