Seven first-year coaching staffs that put in work in the classroom

There are certain things in life that are guaranteed. Death, taxes and a new head coach promising his players will work hard in the classroom are chief among them. Every head coach promises certain things - they'll be good kids, they'll work hard, they'll make this school proud, and they'll bust their rumps in the classroom. 

Thirty new head coaches made that promise a year ago, and with the release of the NCAA's most recent APR scores on Wednesday, we can now say that seven of them delivered in a big way. This isn't to say that the other 23 didn't produce good results. Some quite literally couldn't improve on previous APR scores, like Boston College head coach Steve Adazzio inheriting a team with a 994 APR.

Others, however, weren't so fortunate.

Here are the seven head coaches that produced a jump of at least 20 APR points in their first season on the job.

It's worth noting that half the credit should go to each school's outgoing coaching staffs. The most recent APR numbers cover the 2012-13 academic year, meaning each new staff took over at the midpoint of the school year.
