Average is 16. 27 is putrid. Last year we were average with our backup QB starting most of the year (17th in YPG, 15th in PPG). We have a great TE in Brandon Pettigrew, a young HB in Best who is great at catching balls out of the backfield, a top 3 WR in Calvin Johnson, plus some other nice complementary pieces in Scheffler, Young and Burelson. You can't really call Stafford average since we hardly saw him play all last year; he's more of an unknown. I would say that we'll rank in the top 20 barring copious amounts of injuries.
Props though for rating all 32 teams.
