Detroit moved the Lions and Pistons from the suburbs back to downtown.
Because the move to Pontiac boomeranged when it became majority black. Plus the Silverdome was falling apart (deflating lol).
It's not like space was at a premium in the warehouse district where they built Ford Field and Comerica. I recall the only other competitor was Novi and that was just to distract from what was a done deal downtown.
Meanwhile, Mayor Groot has basically told da Bears to go-on-wich-yo'self out of downtown to tidy-whitey Arlington Heights. You wait and see, Groot will build Cabrini Green North on Soldier Field, overlooking a giant statue of Groot where Adler Planetarium is!
