Being a lifelong Detroit Lions fan makes me somewhat an expert in this category. I have told my biddy for years I think the key to the NFL is protecting the QB, any QB with time in this league can make the throws. On defense the same thing, get to the QB. If you can then you dont stand a chance. Thats how I would build a team.
Passing game
Running game
Run-stopping D
Pass-stopping D
Special teams
Team chemistry
Just want to get a consensus of what people think is most important.
