I'm with you here, that change can't cost too much to make (<10k), so at $5MM a year, maybe NE negotiated some full takeovers.
The current hat create is fine, I guess, but does't feel right for the season, IMO. I prefer something that says it's the BILLS house - big wordmark logo, "Home of the Buffalo Bills" the Championship logos, etc.
Interesting that the add-on above the scoreboard is "New Era Field" (with their logos prominently displayed), does that still leave the door open to "at Ralph Wilson Stadium" underneath it on the actual scoreboard before the season?
