I actually liked the rolling roof design from several years back.
Could you imagine how much louder that place would be if you put a top on it like that?! in all honesty theyll likely build a new stadium some day. Might not be for several years. But it'll happen eventually. Personally love arrowhead and the unique design. It stands out from all the oblong shaped stadiums around the league. But a rolling roof concept would provide shelter from rain and snow, but wouldnt be entirely climate controlled.
