Player Efficiency Ratings

Our returners have lately come to feel like they are entitled to start and/or play major roles without truly working for and earning those roles. I was trying to think of a relatively simple yet effective way of delivering a message to the returners that they needed to produce to earn their minutes. We've tried talking, watching film, running, and a number of things, but nothing worked. The message either was not being received, or they were simply just lazy. I heard a coach once say to a player, "You're either ignorant or defiant. Neither is any good."

I wanted to quantify things. Make it very black and white for them with no gray area. I remember we had a grading system at Eastern Washington that awarded points (both positive and negative) for certain stats that were weighted for what we felt was important. We would add up the points and instead of posting a box score in the locker room, we'd post a single number for each player. The problem with that: A) we'd have to watch the film afterward, B) players didn't get their score until the next day, C) some of the stats were arbitrary and subjective, and D) I can't find that particular grading system. (I'll post it once I dig it up)

So I started calling around to friends and colleagues. What I found was an efficiency grading system that has been used by Oregon Institute of Technology Head Coach, Danny Miles. Coach Miles has a number of accolades next to his name and is a brilliant basketball mind. His efficiency rating is easy to do and can provide instant feedback, even at halftime. This efficiency rating follows:

(Points + Rebounds + [2 x Assists] + [2 x Steals] + [2 x Blocks] + [3 x Charges Drawn])
Divided by
([2 x FG missed] + FT missed + [2 x Turnovers] + [2 x Fouls])

The rating scale is:
Excellent = 1.75 and above
Very Good = 1.5 - 1.74
Good = 1.25 - 1.49
Fair = 1.0 - 1.24
Poor = Less than 1

You can also use this without the charges drawn. That rating scale is:
Excellent = 1.6 and above
Very Good = 1.35 - 1.79
Good = 1.1 - 1.34
Fair = 0.85 - 1.09
Poor = Less than 0.84

The thing I really like about this system, is that it is very objective and takes minutes played out of the equation. It emphasizes to players that they have to be productive, no matter how many minutes they play. I tweeted last night, "Basketball isn't like AT&T. There is no such thing as roll over minutes. Use 'em or lose 'em."
