The salary cap era in many cases does not allow you to field a complete team. Just look at the numbers, we have not had a repeat champion since 2004/2005. Go back to 96 when we beat NE only Baltimore, Denver, NYG & Pittsburgh have multiple titles and I can argue that Baltimore did not have a HOF caliber QB and Eli is what he is. Hell Brad Johnson and Nick Foles won SB’s. Rex Grossman played in one.
In today’s world you are forced in many cases to spend on 3 premium positions, QB, LT & a rush end or LB and maybe you can add CB to that list. The rest is unfortunately draft and develop for the most part because you can’t spend like a hedge fund to bring in FA. As a matter of fact i don’t know if there was a complete team on both sides of the ball that has won in recent memory
Would I like more trophies sure we all would but it’s not a simple formula.
