is scaling from 0 to 1 based on worst and best a norm in the NFL stats field? I feel like doing a more typical scaling based on z-score (0 is league average, value is based on standard deviations from mean, no theoretical bounds) would be better, since one team doing especially well/badly can make the other teams seem significantly worse/better than they actually might be (you especially see this in the first weeks with the red dashed lines)
