A lot of northern United States sports teams have constructed indoor stadiums for their teams. There are two thoughts concerning this: makes sense with winter climates, and no thank you because it takes away the tradition of the game that should be played under these extreme conditions.
It seems the Browns are in the beginning stages of conducting feasibility studies to see if a new stadium could be on the horizon for the franchise. Their current lease expires in 2028.
According to a report on neo-trans.blog, two sources close to the Haslam Sports Group have stated that the Browns are looking into building a new venue centered around a ballpark village instead of costly renovations to FirstEnergy Stadium.
