I haven't read the other responses yet....my knee jerk response?
Herm is right.
21-24 points is a very good NFL effort.
If you score more than 21 points or more, on average...one of the following three things is true:
1. You have an OUTSTANDING offense, capable of hanging 30 point on ANYONE. (Vermeil's teams)
2. You are facing a defense that several NFL teams will LIKELY hang 30 points on. (Vermeil's teams)
3. You got turn-overs/breaks/defensive scores that obscure an otherwise average offensive effort. (Marty's teams)
Pretty simple really.
Only Arena league teams EXPECT 24 or more points a week. In the NFL, Defense SHOULD mean something....
