Two main factors. One, the percentage of times you get a shot after the other team does. Your percentage goes down here if the other team gets offensive rebounds. It goes down if you turn the ball over. Whether you attmept a shot, or whether you get to the line, I cound that as an attempt for this stat. This factor to be exact goes like this: (Your shot attempts + your free throw attempts divided by 2.3) all divided by (your opponents shot attempts + your opponents free throws divided by 2.3) The 2nd factor is what percentage of your shots you make. For this, if you make 2 free throws, I count that as a made shot attempt. I also divide the number of your made threes by 2 and give you still more credit for made shots. For the denominator, its your shot attempts plus your free throw attempts divided by 2.3. This 2nd factor goes like this: (Your makes + your 3's made divided by 2 + your free throws made divided by 2) all divided by (your shot attempts + your free throw attempts divided by 2.3) Multiplying the two factors together gives you this new stat of mine. Defensive / offensive efficiency. Irvine, 50.8%, opp 50.3% Carlisle first year, 52.9%, opp 52.8% Carlisle 2nd year, 50.2%, opp 52.8% Brown first year, 47.9%, opp 51.8% Brown 2nd year, 49.9%, opp 52.6% So far Flip's first year, 49.7%. opp 57.5% Irvine's differential was a negative 1/2 percent, and his team did terrible. Carlisle in his first year was dead even, barely squeaked by Toronto and got pounded by Boston. Carlisle's 2nd year saw a bit of a positive differential and we got further in the playoffs. Brown had good differentials both years, and outstanding results. Flip so far is 9-1, with the best differential by far among the 6 years looked at. Some verbage I posted on this earlier in case it might help to show where I am coming from on this: Defensive / offensive efficiency. As a defensive stat, you look at effective shooting percentage by the other team based on your own number of shot attempts. As an offensive stat, well, you just use the exact same thing, but from the perspective of your opponents. So its just one number for you, and one for your opponents. This stat takes into account game pace, because its based on your own shot attempts. It takes into account your offensive rebounds. If you get a lot of offensive rebounds, you get a lot more shot attempts. Since I am dividing the opponents number by our shot attempts, it makes them look bad the more offensive rebounds we get. Free throws are taken into account twice. Once when figuring our number of shot attempts. If we got fouled every time down, and only scored at the line, we would have zero shot attempts for the year, but this stat would still work, as I factor in free throw attempts as shot attempts. There is more to this, but I am out of time for the moment. For now, I will just mention that our current team is effectively scoring 58% of the time after a shot attempt by the other team. This compares to our opponents at 50%. I have figured this all back for five year. I will post more later on this.
