(Old) Notes:

- This is not a ranking of who is the better coach, it's only meant to judge past success.
- I gave Arians credit for the 2012 Colts, when he coached 12 games with Pagano out.
- keep in mind that Marv's first 8 seasons featured as many 4 win seasons as playoff berths. That hurt his grade, but it happened.

Explanation of grading:

A few years ago - in response to a certain poster who claimed that Marvin Lewis was one of the most successful coaches - I created a grading system to compare Marv's entire tenure to how the rest of the teams fared over the same stretch. I graded each season and added all the points together. The grading system looked like this:

+8 points for 12-16 regular season wins
+5 points for 10-11 wins
+3 for a 9-7 season
0 points for 8-8
-3 for a 7-9 season
-5 for 5-6 wins
-8 for 4 or fewer wins

I added the following bonuses:

+10 for a division title
+10 for each playoff win
+50 for a Super Bowl title

For example, Marv accumulated +18 points in without winning a playoff game, while he got a -5 grade for 2016. A 9-7 team that fails to win it's division, but wins 1 playoff game would accumulate a +13 score. Championship teams usually rack up a +85 score or higher. Not a perfect system, but IMO it's fair. Obviously if you make a deep playoff run or win a title, you should be heavily rewarded. You can also rack up points by winning in regular season and capturing division titles.

This time around, I figured I'd finally take Berserker's advice, and make it more of a coach to coach comparison. In order to do this, I graded every single season by every single current Head Coach. Fortunately, Pro Football Reference has all the information I needed on each coach's page, as it made accumulating the grades go much faster. In order to make the grades fair for comparison, I took each coach's total career points and divided them by total years coached. So the grades are a per season average.
