Analyzing the impact of Johnson's seven-game coaching adjustments

Johnson said his staff conducts seven game evaluations which involve everything from coaching decisions to player evaluations. After every seven games so far this season Johnson has mentioned a few adjustments that he has made, and for the most part Johnson's method seems to be working.

After the first seven games Johnson said he identified offensive rebounding as an area his team needed to improve on going forward. The shifting focus showed up immediately as Alabama grabbed 21 offensive rebounds in the Crimson Tide's victory over Clemson. 

In Alabama's first seven games the team grabbed 52 offensive rebounds for an average of 7.43 per game. In the next seven games Alabama grabbed 77 offensive rebounds for an average of 11 per game. When dealing with smaller sample sizes it huge variations like the Clemson game could skew data, and the first seven games also included an outing against Southern Mississippi in which the Crimson Tide only grabbed a single offensive board.

When those two extremes are eliminated the data change is less extreme. In the first six games Alabama grabbed 51 offensive rebounds for an average of 8.5 per game compared to Alabama's 9th-14th games where the team grabbed 56 offensive rebounds for an average 9.33 per game. 

After the Crimson Tide lost to Kentucky, Avery Johnson's next big change was to insert Riley Norris into the starting lineup. In games Norris contributes a lot to the team, but for the sake of this argument let's focus on the teams points scored and points allowed. 

In Alabama's first 14 games the team scored 912 points in regulation for an average of 65.14 points. In the eight games Norris has started since the team has scored a total of 553 points for an average of 69.13 points. 

Again as with Clemson we see an immediate change as Norris scored a career-high 27 points against South Carolina in a home game that saw Norris start 7-7 from beyond the arc. 

As good as Norris has been for the Crimson Tide's offense lately, Johnson also frequently praises his skill as a defender. 

Alabama's first 14 opponents scored 854 points for an average of 61 points per game. In the last eight games Alabama's opponents scored a total of 545 points for an average of 68.13 points per game. Here, we see the defense allowing more points per game, but its hardly a fair comparison since the strength of the two stretches are difficult to properly evaluate. 

The data seems to suggest that Johnson's adjustments help Alabama, but as expected the team doesn't see an incredible jump in any noticeable area statistically.
