Right, but see you're thinking about this thing entirely the wrong way. You are talking about making moves and trying to do things that might actually help you win games. Taking risks, acquiring undervalued skill guys, building a team from the inside out....you'll never get hired by the Fords that way.
You have to look at this like William Clay Ford and his idiot spawn Bill Jr: Detroit is a loyal sports town that loves their teams and supports the Lions come hell or high water. If revenues are currently in the neighborhood of 75-80% of what they would be if you fielded a winning (or at least semi-competitive) team, and it would take a huge investment of capital - say, $35-40 mil extra all-in - to improve the team, is it worth it to garner that extra 15-20% in revenues? The balance sheet tells you the red outweighs the black in that situation, so you don't bother spending the extra dough. Simple.
Also, even if/when they do try to win, they are so insanely stupid they just don't know how. I mean, look how they ran the car company for the past 3 decades: slow, steady, inexorable march toward mediocre/bad. The Fords just aren't winners by any definition in any realm (sports, business, life...); if their last name weren't "Ford", they'd probably be slinging you your morning McGriddle at the drive-through. Total incompetence reigns, with no hope on the horizon: until the Fords sell the team (which will never happen in a million years), the Lions will never be a winner.
