I just think the Bidwills figured out a long time ago they could make money without a whole lot of effort if they just did things their way. Their potential return was lower, but they took no risk because they could always pay the players with the cap money, have some left over etc. They never felt they HAD to take the risk to try and hit it big.
That's been changing for years now as we joined the modern age of the NFL, we're not totally there yet but we are headed the right direction.
Obviously having the promise of the stadium revenue helped push us that direction again they KNEW they couldn't lose money so they took a few more risks than normal.
I think you are spot on.
I believe few of us would risk $1000 to make $1005. For many years, the Bidwills did the same.
I also believe few of us would agree that the Bidwills are doing business the same way they have their entire time in Arizona. The times, they are a changin'.
