One more playoff appearance this year or next will erase the culture objection.
We've seen that spending big on free agents guarantees nothing. Adding veterans is something you do when you are nipping on the heels of a Superbowl. The Pats only bring in bargain basement guys. The Steelers never get into spending wars. The chronic overspenders (Bears, Dolphins, Raiders) never win.
We've managed to retain a great player like Kyle Williams who stays by choice. Not everyone wants to spend weekends in Times Square.
The Packers are the right comparison. Get the QB right and all else flows from that.
