Regression Model 4: Analysis of West Coast Offense or Not, Strength of Schedule (SoS), and Offensive and Defensive Productions on Number of Concussions by Offensive Players During the 2012-2014 National Football League Regular Seasonsa
| Predictor | B (SE) | β | t | P | r 2 | sr 2 |
|---|---|---|---|---|---|---|
| West Coast offense | 0.926 (0.435) | 0.438 | 2.128 | .043 | 0.248 | 0.114 |
| SoS | –0.288 (0.165) | –0.291 | –1.746 | .092 | 0.089 | 0.076 |
| EXP-Pass- Offense | –0.001 (0.003) | –0.093 | –0.476 | .638 | 0.033 | 0.006 |
| EXP-Rush- Offense | 0.001 (0.011) | 0.016 | 0.083 | .934 | 0.035 | <0.001 |
aOffensive players include running backs, fullbacks, quarterbacks, centers, offensive guards, offensive tackles, tight ends, and wide receivers. Dependent variable = number of concussions; F(4, 27) = 3.250; P = .027; R 2 = 0.325; adjusted R 2 = 0.225. B, regression coefficient; EXP-Pass-Offense, expected points contributed by passing offense; EXP-Rush-Offense, expected points contributed by rushing offense; SE, standard error.
