They are shelling out millions in the process of preparing for the new stadium and will likely have to spend hundreds of millions more. I do not put I past them to tell him to field a team far below the cap to increase profits. That’s is the only logical explanation for him to continue to let homegrown talent walk instead of giving extension, unless he is a complete incompetent fool which is also possible.
Also people act like the Bears don't spend lol we do spend it's just not always wisely allocated or pans out. Being cheap in the NFL like in other leagues isn't the same, teams spend the money it's just a hard cap genuinely means you are less reckless with it because their is no luxury tax/etc.
