The continued media coverage of the Bears' bass ackwards approach in courting other Chicago suburbs makes it astonishingly clear just how stupid they are.
Rather than announce an intention to leave Soldier Field and open up a potential bidding war between municipalities across the country prior to purchasing or committing to a new lease, they immediately jumped on the Arlington property, purchased it for nearly $200m, started demolition, and then decided they wanted to start up a bidding war because they didn't secure preferential tax treatment prior to the purchase.
I get that they could conceivably develop, divide, and sell off the Arlington property at a profit, but that would require a serious long term commitment of cash flow to non-football operations, and it also would require the Bears to seek additional financing for the purchase and development of a different parcel (or the redevelopment of Soldier Field) when the public funding of stadium construction can be political suicide. It's not like the McCaskeys are independently wealthy and have bags full of money they could throw around or extensive collateral they could put up for secured financing.
The only theory that makes sense to how all of this happened is the Amazon purchasing Arlington rumors had legs, which caused the Bears to panic and accelerate their timeline for purchasing Arlington, rather than taking the time to exercise due diligence, build local political support, and secure commitments for preferential tax treatment prior to purchase.
In other words, they pulled a Trubisky.
